Diocletian's Palace in Split: Undiscovered Roman Ruins & Hidden Passageways
Best things to do in Split: fall for Dalmatia’s timeless charm as this travel guide leads history lovers through the city’s ancient alleys, palaces and hidden ruins.
Updated | June 2026
Why You’ll Fall for Split
Officially the Republic of Croatia, Croatia sits where Central Europe meets the Balkans, its entire coastline opening onto the Adriatic Sea. Rugged and radiant, the country is famed for sun-drenched beaches, medieval fortresses and a rocky coast that looks ready-made for television epics. Seafood and local wine are reasons enough to visit; the clear, often brisk waters and near-constant sunshine are pleasant bonuses.
Historically called Spalato, Split is Croatia’s second-largest city and a bridge between ancient and modern life. Founded around the late Roman Emperor Diocletian’s retirement palace, the city grew from that imperial compound into a bustling port and urban center. Diocletian’s Palace remains the beating heart of Split — an extraordinary, millennia-old labyrinth of courtyards, cellars and narrow streets where people still live and work among the ruins.
From Split’s eastern Adriatic shore you can island-hop across the Dalmatian coast’s thousand-plus islands. In about an hour by speedboat you can reach the Blue Cave, a sea cave that glows with surreal blue light on sunny days. On Vis, the secluded Stiniva Cove hides behind a narrow rock mouth and must be reached by small boat or by swimming. The Blue Lagoon offers tranquil, crystalline waters for swimming and sunbathing, while Hvar — one of the larger islands — pairs a lively nightlife with a handsome historic center and excellent food.
Split’s mix of layered history and easy access to island secrets makes it a uniquely compelling base for exploring Dalmatia.
Two-Week Travel Itinerary
I spent a few delightful weeks roaming Croatia and Montenegro. My journey began in Dubrovnik, the “Pearl of the Adriatic,” then I slipped across the border for a day trip to Mostar in Bosnia and Herzegovina, a little Balkan jewel with a bridge that feels like a storybook come to life.
From Dubrovnik, I rode the ferry north to Split, a sun-warmed Dalmatian city where Roman ruins peek out from between lemon trees. A speedboat whisked me away to the luminous Blue Cave and a scatter of shimmering islands.
Nature called next at Plitviče Lakes National Park — a spellbinding forest of 16 terraced lakes and cascading waterfalls carved into a vast limestone canyon. On my way out of Croatia, I passed through lively Zagreb before flying to Podgorica.
From there, I followed the Adriatic coast to the medieval walled town of Kotor, my base for day trips into Montenegro’s dramatic interior: the rugged beauty of Durmitor and Tara Canyon, the serene holiness of Ostrog Monastery and the sweeping views and history around Lovćen’s Mausoleum, the Royal Old Capital and tranquil Skadar Lake.
For this guide, and most of my trips, I approach a new place like a curious wanderer. Usually, I give each new town about three days to work its magic — sometimes a little more, sometimes a little less.
After landing, I spend the first day on foot, soaking in the town’s small rituals and everyday rhythms. I carry a loose checklist of places I’d like to see but mostly I let my feet decide, which always leads to delightful, unexpected encounters. Day two is reserved for a longer outing — a day trip, a special event or a farther-flung site — leaving the final day to slow down, revisit anything I missed and dream up the next adventure.
Split was no exception. Join me as I wander through Split’s ancient streets, tripping over history and marveling at sunlit seaside ruins.

Split for the History Lover: Wandering Diocletian’s Palace, Roman Ruins & Timeless Adriatic Stories
Wander through Split’s sunlit alleys where ancient Roman walls meet a bustling waterfront café scene and savor seaside sunsets, fresh seafood and centuries of Dalmatian charm. Let Diocletian’s Palace lead you from hidden courtyards to lively markets — perfect for slow exploration and unexpected discoveries.
With just three days in Split — one spent island hopping and another lost to food poisoning — I had a single sunlit day to wander the city. Come stroll with me: a history-lover’s walking tour through stone streets, hidden courtyards and seaside views, topped off with a few irresistible bites along the way.
01 | How to Get to Split
Split sits like a sun-warmed gateway on Croatia’s central Dalmatian coast — a short sail or drive south of Zadar, north of Dubrovnik, and an easy island-hop from Hvar — and travelers most often reach it by plane, ferry, bus, car or catamaran, with scenic coastal views, ancient towns and shimmering Adriatic islands unfolding along the way.
Plane | Fly into Split Airport (SPU) from a variety of international destinations — either direct or with connections through hubs like Zagreb, Vienna or London — and expect flight times to vary: about 35–45 minutes from Zagreb and roughly 1–3 hours from most other European cities.
Fares also fluctuate by route and season; a domestic or regional hop such as Zagreb–Split typically runs €40–120 ($44–132 USD), while international tickets often range from €50 up to €300 or more ($55–330+ USD).
On your final approach you’ll often be treated to sweeping coastal panoramas of the Adriatic, nearby islands and the marble roofs of Split, while flights from Zagreb cross inland plains and rolling hills.
Bus (Long Distance Coach) | Taking a long-distance coach is an easy, scenic way to reach Split from cities like Zagreb, Zadar, Dubrovnik, Šibenik and even Mostar in Bosnia. The journey times vary — roughly 4½–5½ hours from Zagreb, about 1½–2 hours from Zadar and around 3½–4½ hours from Dubrovnik, although traffic can add to the Dubrovnik trip.
Fares are reasonable: expect to pay about HRK 120–200 ($18–30 USD) from Zagreb or Dubrovnik and HRK 40–80 ($6–12 USD) from Zadar.
Along the way you’ll pass stretches of Dalmatian hinterland, pine-covered limestone hills and, as the coach descends toward the sea, sweeping seaside vistas dotted with small coastal towns and busy little ports.
Car | Driving to Split from other parts of Croatia is straightforward and rewarding: from Zagreb the trip via the A1 motorway takes about 4–5 hours, from Zadar roughly 1.5–2 hours and from Dubrovnik approximately 3.5–4.5 hours depending on border waits, traffic and whether you use the Pelješac Bridge route.
Expect to pay for fuel and tolls — fuel runs about HRK 12–15 per liter (around $1.80–2.30 USD per liter; $6.81–8.71 USD per US gallon) and tolls on the Zagreb–Split route are roughly HRK 120–200 ($18–30 USD), while rental cars vary widely in price, typically between €30 and €90 per day.
The drive treats you to dramatic mountain passes, archaeological ruins, olive groves, coastal cliffs and sweeping island views from scenic overlooks, and gives you the freedom to stop in charming historic towns like Šibenik or Trogir along the way.
Ferry or Car Ferry | Ferries and car ferries run from nearby islands like Brač, Hvar and Vis to Split, with the Brač (Supetar) crossing taking about 50 minutes, the Hvar (Stari Grad) trip lasting roughly 1.5 to 2.5 hours depending on the service and the Vis crossing about 2 to 2.5 hours.
Passenger fares generally range from HRK 30 to 120 (around $4.50–18 USD), while tickets for a car plus passengers are higher — typically HRK 150 to 500 (about $22–75 USD) depending on route and seaso.
Along the way you’ll enjoy close-up views of island coastlines, fishing villages, turquoise bays and the approach to Split’s harbor and lively Riva promenade.
Catamaran or Fast Ferry (Passenger Only) | You can travel by catamaran or passenger-only fast ferry from Hvar, Korčula, Dubrovnik (seasonal), Bol on Brač and other Dalmatian islands; the trip from Hvar to Split takes about one to one-and-a-half hours, Korčula to Split about two to three hours and the seasonal high-speed service from Dubrovnik to Split roughly three to four hours.
Fares generally range from HRK 80 to 250 (about $12–37 USD) depending on distance and season and along the way you’ll enjoy open-sea crossings with island-dotted vistas, the occasional dolphin sighting and clear views of Split’s waterfront as you approach.
Train | Taking the train from Zagreb to Split is a relaxed, if somewhat slow, option: services are limited and you may need to connect by bus, with the journey typically taking around six to eight hours — trains are slower and less frequent than buses.
Expect to pay roughly HRK 100–200 (about $15–30 USD) and enjoy a scenic ride through inland countryside, river valleys and small towns for a more leisurely, less coastal-oriented route.
02 | Arrive in Split & Gorge on Delicious Pizza
Reaching Split can turn into a little seaside adventure. My route — I set off from Dubrovnik and boarded a coastal ship for just $12 USD. The five-hour trip felt like a slow, scenic parade, pausing at island stops — Pomena, Korčula, Hvar, Milna — before finally arriving in Split. The ride was delightful and a friendly crew member even let me stand on the bow by the captain’s chair to breathe in the salt air. It felt gloriously special, until the open sea breeze turned sharp and I ran inside to warm up.
When the boat slid into Split, we spilled out in a slow, sleepy procession. I meandered into town at my own unhurried pace and arrived at Hostel Dvor in about fifteen minutes. The route was easygoing — until the cobbles began. My suitcase and I had a gentle tango, bumping over each stone as if the street itself were keeping time.
Tip | Once the ferry docks in Split, it’s usually just a 10–15 minute stroll into town to reach your accommodation. A quick note: the city’s cobblestone streets add to its charm but they can make rolling suitcases a bit of an adventure — consider a softer-wheeled bag or a backpack for an easier walk.
Famished and irritable, I set off on foot as the light waned, worrying that kitchens might be shutting. Fortune smiled on me in Old Town, where I stumbled upon the charming Mediterraneo Restaurant & Pizzeria. Seated outdoors, I tucked into a Greek salad dotted with generous clouds of fresh feta and a large pizza piled with olives, artichokes and prosciutto. It was pure perfection — I devoured every last bite with unabashed delight.
Tip | If you roll into Split late, don’t wait — grab a bite and start your evening. Many kitchens wind down around 10 p.m. but a handful of fast-food spots and kebab joints keep the lights on later. You can also summon dinner to your door with delivery apps like Wolt or Glovo.
03 | Savor a Delightful Brunch at Ciri Biri Bela
Begin your morning with a wholesome breakfast — you’ll want fuel for the day’s discoveries. My first day in a new city always feels a little like unwrapping a gift. With no expectations, I lace up my shoes, step outside and let the streets lead me. Wandering around helps me learn the city’s layout; along the way, I make a mental list of places that catch my eye and allow the day to unfurl at its own gentle pace.
Ciri Biri Bela sits in Varoš, one of Split’s oldest, most authentic neighborhoods — perched on the fringe of the historic old town and tucked just behind the Croatian National Theatre. Family-run and named after a catchy Dalmatian song that charms both young and old, the restaurant aims to charm visitors in the same way.
Slip beyond a thick white stone wall, descend a few steps beneath street level and find yourself in a lovely courtyard. Settle into a seat and breathe in the calm, ready for whatever the day will bring.
Discover an eclectic menu that marries sun-kissed Mediterranean flavors with rustic Dalmatian charm, all centered on fresh, organic and locally sourced ingredients. Ćiri Biri Bela has earned a reputation for outstanding breakfast, brunch and dinner — everything made with care, often using produce and goods from the family farm.
Mornings and late mornings are a highlight: picture sunny-side-up Sunny Chilli Cheese Eggs on sourdough with creamy avocado and a drizzle of chilli oil, fluffy organic omelettes, house-made granola and indulgent sweet or savory breakfast boards. For lunch and dinner, expect comforting local classics alongside shareable, tapas-style plates — think black octopus risotto, slow-cooked veal, tender lamb chops, parmesan-crusted chicken and a rotating selection of small plates meant for savoring and passing around.
The menu is thoughtful and inclusive, with plenty of vegetarian, vegan and gluten-free choices — from vibrant vegan bruschetta to hearty baked potatoes and a delightful veggie pastry pizza. Finish with a treat: freshly squeezed juices, a matcha bowl, locally roasted coffee, regional wines and house-baked pastries like pistachio or salted caramel pancakes that make the perfect ending to any meal.
My order arrived like a little celebration, artfully arranged on wood-carved boards and in lovely ceramic dishes. The spread — complete with a dirty chai latte and a Women’s Health platter — offered an array of irresistible bites: freshly baked French bread, fried eggs, vanilla yogurt topped with fruit and nuts, smoked salmon with wasabi cream cheese, an assortment of cheeses, jams and butter, plus grapes, apricots, cantaloupe and kiwi. It was almost too pretty to dig into.
Every bite was fresh and flavorful, and the service was warm and attentive. I couldn't resist taking an almond croissant home, crafted by their in-house French baker.

05 | Stroll Along the Seaside Riva & Enter Diocletian's Cellars
The Adriatic unfurls against Split like a gentle hello — its shimmering waters kissing the city with easy warmth. Yachts and larger boats dot the horizon, moored respectfully at a distance so their presence feels poetic rather than intrusive. Calm and glassy, the sea laps quietly beside the Riva, the city’s beloved waterfront promenade: a sun-washed terrace of palms, marble stones worn soft by generations of footsteps, cafes spilling out tables and laughter and benches that invite slow conversation. Strolling the Riva at any hour, you’ll find locals sipping coffee, vendors selling fragrant pineapples and sea-breeze souvenirs and an open view that frames the harbor’s graceful boats like scene-stealers in an everyday coastal play.
The Riva is Split’s elegant, palm‑lined promenade, its graceful curve taking shape two centuries ago under the watch of Marshal Marmont when Napoleonic France held sway. It’s the city’s front porch — an irresistible place for a morning espresso or a leisurely evening wander by the Adriatic. Alongside the seafront stands the south facade of Diocletian’s Palace, its doorway spilling straight into the mysterious vaulted cellars below.
Split’s story begins as the Greek settlement of Aspálathos in the 2nd or 3rd century BCE but it truly blooms with the arrival of the Roman emperor Diocletian in 305 CE. Determined to restore order to a sprawling empire, Diocletian devised the Tetrarchy — a bold experiment in shared rule where four leaders each governed a quarter of Rome and stepped down after twenty years. The system faltered in practice, yet Diocletian himself honored the plan: after two decades he retired to a lavish palace on the Adriatic coast and spent his remaining ten years in quiet seclusion, passing away of natural causes.
Centuries later, when the nearby city of Salona fell to invaders from the east, its people poured into Diocletian’s palace for refuge. That migration is when Split, as a living city, truly came into being — built layer upon layer around the imperial complex. Today, a bronze model on the Riva captures Split’s rich, evolving silhouette: a city shaped by emperors, refugees and centuries of additions, each era leaving its charming mark.
Most striking, facing the sea, is the palace’s southern facade — crafted as the Emperor’s private outlook toward the open water. The architect imagined a link between palace and seascape: a long arcade of windows that breathe onto the Riva and the Adriatic beyond. At first, the wall seems curious, even odd, but it rises proudly, studded with shops and tucked-away balconies that lean out to watch the tide.
Diocletian’s Palace, a UNESCO World Heritage site since 1979, dates to the late third century AD and today makes up roughly half of Split’s old town. Carved from local limestone and white marble, much of the palace survives in remarkably good condition — especially the exterior walls, with the curious exception of the western side.
Legend has it that the emperor wanted to step straight from his ship onto the palace without ever leaving the deck, so the lower levels were once lapped by the sea. As the water slowly receded, the city we know took shape.
Though described as a “palace” and intended as Diocletian’s retirement home, the complex feels more like a vast fortress than a cozy villa. It originally had four gates; three still stand. The southern quarter served as the residential wing, the center hosted religious and ceremonial life and the northern sections housed soldiers, servants and possibly slaves. The Southern Gate — sometimes called the Bronze Gate — likely provided direct access for goods arriving by boat and beyond it lie the cool, shadowy cellar basements that hint at the palace’s bustling past.
The cellars of Diocletian’s Palace are the world’s largest surviving Roman indoor space and one of the most remarkably preserved complexes of their kind. It’s largely thanks to this subterranean maze that Split’s historic center earned its spot on the UNESCO World Heritage List.
The construction blends ancient Roman engineering with subtle eastern influences. In antiquity, the cellars lifted the emperor’s living quarters above and served as the palace’s storage and service area. As the most intact covered space from that era, the cellars offer a vivid glimpse into the layout and look of the imperial chambers that once stood overhead.
Over the centuries the cellars have led many lives. In the early Middle Ages, some chambers served as homes, while one great hall hummed with the press of oil and wine — the original turnjačica (wine press) still stands there as a proud reminder. As the palace rose, the basement fell into humbler use, becoming a convenient dump for the households above.
In the mid-19th century architect Vicko Andrić rescued the space, carefully excavating and reshaping the vaults into the elegant cellars we see today. The eastern wing, though, remained hidden until it finally welcomed visitors in May 1995.
Today, the cellars hum with life. They host a lively mix of art shows, theater evenings and culinary and wine events but on ordinary days they become a bustling market and an improvised gallery. Descending into the space feels like slipping into a secret theater of stone: low light and a gentle dampness only add to the atmosphere as lofty arched ceilings soar overhead and sturdy square columns climb up to meet them. Cool, misty air drifts between stalls where vendors, nestled in the shadow of those pillars, display handcrafted treasures with easy cheer.
The central hall — the main corridor — unfurls from the Riva toward a flight of stone steps that ascend into the palace’s sunlit courtyard and the Peristyle, where a graceful ring of columns embraces the open heart of the estate.
06 | Praise the Peristyle — the Monumental Central Courtyard of Diocletian's Palace
The inner courtyard of Diocletian’s Palace opens into a graceful Roman Peristyle, its columned gallery folding around the space like an elegant frame. At one end stands the prothynon — the porch where the emperor’s throne once claimed pride of place — and nearby, an arched portal still slips straight into the former imperial chambers. To the south, the private apartments once extended into a shadowed cryptoporticus, a broad arcaded corridor that looked out over the glittering sea, and a cluster of baths whose weathered remains whisper of long-ago rituals of leisure.
Emperor Diocletian, hailed as Jupiter’s own living son, would stand beneath the central prothyon’s arch as his subjects approached in ritual: some bending to kiss the hem of his crimson cloak, others sinking to their knees and many casting themselves fully upon the earth in reverent adoration.
Today, the central square of Diocletian's Palace is the bustling heart of the old city — a sun-warmed plaza where chatter and footsteps form a steady, comforting hum. Tour groups cluster beneath the shadow of ancient columns, friends swap stories over espresso at tiny stone tables and elderly residents sit on the worn steps, fingers tracing the centuries-old carvings.
Street musicians thread melodies between the alleys, while artists capture the square’s light on canvases propped against the walls. At any hour, people gather here to meet, to linger, to watch the world move through this extraordinary meeting place where imperial stone meets everyday life.
After Diocletian’s death, the city largely fell silent. The palace, however, stayed in imperial hands, a refuge for exiled members of the emperor’s family. Diocletian’s remains rested in the mausoleum tucked inside the palace walls. It wasn’t until the 7th century that life stirred again and new buildings began to rise. Over the centuries, the city’s name shifted with its people — Italians knew it as Spalato and later the Slavic Croats who settled there gave it the name Split.
Sometime around then, Diocletian’s mausoleum was gently transformed into a Christian church crowned by a graceful five-tiered bell tower — the Romanesque spire of the Cathedral of Saint Domnius. Over the years, traces of the ancient world were gradually lost: artifacts vanished, stonework was altered and even Diocletian’s own sarcophagus slipped away from the old tomb, its fate left to the mysteries of time.
After absorbing the Peristyle in its entirety, drift deeper into the site, eyes alight. At the back, ruins unfurl endlessly, arcades reach up toward the clear blue. Artists display paintings on easels as curious visitors linger, some striking poses in the main courtyard while others settle onto purple cushions to savor the scene.
The palace sits within an irregular rectangle, its silhouette softened by 16 octagonal towers that punctuate the northern, eastern and western faces. Each facade is pierced at its center by a grand gate that opens into a sheltered courtyard. To the east, come upon the Silver Gate — Porta Orientalis — a once-secondary entrance that nonetheless turns its face toward the old Roman town of Epetia, as if keeping a quiet watch over its distant neighbor.
Around the 6th century, a little church was lovingly raised above the East Gate and dedicated to St. Apolinar, its presence likely a gentle response to the flow of refugees arriving from distant places. Matching its quiet grace, small chapels soon crowned the other gates as well: the Golden Gate to the north, the Iron Gate to the west and the Bronze Gate to the south.
From the central courtyard, tucked gems await — some I only discovered later, like the Treasury and the Baptistry. You can also climb the vestibule for sweeping city views and pleasantly smaller crowds.
The Treasury is a small, enchanting museum that houses an intimate collection spanning from the palace’s earliest days through the 18th century. Stepping inside feels like slipping into a pocket of time: gilded reliquaries, delicate icons and hand-forged liturgical vessels sit alongside embroidered vestments and age-darkened manuscripts.
Many pieces reflect the palace’s religious life — ornate crosses, chalices with patinaed silver and jeweled monstrances that once sparkled in candlelight. Labels note provenance and occasional restorations, while soft lighting and warm wood display cases bring out the subtle craftsmanship and sacred aura of each object.
Together, these treasures sketch a layered story of devotion, artistry and the changing rites of court worship across centuries.
The Baptistry, also known as the Temple of Jupiter, sits tucked in the western quarter of Diocletian’s Palace, reached by a short, atmospheric lane that leads away from the bustling Peristyle.
Erected between 295 and 305 CE, the structure was originally devoted to Jupiter, Rome’s chief deity, and its compact, octagonal form and richly carved stonework still betray that imperial ambition. Inside, a soaring central dome crowns a circular space ringed by Corinthian columns; sunlight filters through clerestory openings, picking out scenes of myth and power in the faded reliefs.
Over the centuries, the temple has worn many faces — converted into a Christian baptistry, its marble floors and ancient sculptures were adapted and reinterpreted, so that today visitors can read layers of history in the worn steps, the reused Roman fragments and the quietly resonant interior where chanting once echoed.
Small details reward close attention: the remnants of classical iconography tucked into later masonry, the centuries-worn capitals and the way the space constricts from the lively light of the Peristyle into a calm, shadowed sanctum that invites a slower, more intimate encounter with Split’s past.
One of a dozen black sphinxes transported from Egypt by Emperor Diocletian keeps a silent, mysterious vigil at the entrance — its smooth, dark stone polished by centuries of hands and weather. Once a symbol of imperial power and exotic wonder, this particular sphinx now frames the threshold to a small Christian chapel, an unlikely but beguiling meeting of ancient Egyptian iconography and early medieval piety.
The site itself likely took on the role of a baptistry in the 6th century, a period of adaptation and sacred reuse when the old imperial complexes were reshaped to meet Christian needs. Around the same time, architects carved out the intimate crypt dedicated to St. Thomas, their stonework folding new layers of devotion beneath the city.
Together the sphinx, the baptistry and the crypt create a quiet scroll — where imperial ambition, pagan artistry and Christian ritual overlap in a single, resonant space.
Wandering through the sunlit central courtyard of Diocletian’s Palace is free to enjoy. To explore the palace’s interior treasures, you’ll need one of the color-coded tickets. Current prices and what they include are:
Blue ticket — €7 / $8 USD: Cathedral, Crypt, Baptistery
Red ticket — €8 / $9 USD: Cathedral, Crypt, Baptistery, Treasury
Green ticket — €10 / $11 USD: Cathedral, Bell Tower, Treasury
Purple ticket — €11 / $12 USD: Cathedral, Crypt, Baptistery, Treasury, Bell Tower
A few practical details to make your visit smoother:
Tickets can be purchased at the official ticket office near the cathedral entrance; in high season, there’s often a line, so arrive early or late afternoon to avoid crowds.
Some sites (especially the Bell Tower and Treasury) have limited capacity and may sell out during peak hours — if you have a firm schedule, consider buying tickets in advance where available.
Combined-ticket options above give small savings and let you move between sites without repurchasing; keep your ticket with you, as it’s checked at each entrance.
There are reduced rates for children, students and seniors — bring ID to qualify.
Opening hours vary seasonally; check the current schedule before you go to plan the best time for rooftop views from the Bell Tower.
With a little planning, you can linger in the courtyard, then step inside to uncover centuries of history — each ticket opens a different chapter of the palace’s story.
07 | Show Reverence at Cathedral of Saint Domnius
The Cathedral of Saint Domnius — called Sveti Dujam or Sveti Duje by locals — is Split’s beloved Catholic cathedral. Serving as the heart of the Archdiocese of Split-Makarska, it combines an Imperial Roman mausoleum and a soaring bell tower into a singular, enchanting church complex. The main church is devoted with quiet reverence to the Virgin Mary, while the bell tower stands as a proud tribute to Saint Dominius.
With its entrance opening onto the eastern side of the Peristyle, the Cathedral unfolds in three distinct chapters, each from a different era. At its heart, lies Emperor Diocletian’s mausoleum, a late-3rd-century jewel fashioned from local white limestone and marble to match the palace that surrounds it. In the 17th century, a choir was grafted onto the mausoleum’s east, its builders removing the eastern wall to marry the two spaces into one. Later still, a Romanesque bell tower rose above the site around 1100 AD, adding a vertical punctuation to the layered history.
The instant you step into the cathedral, a hush wraps around you. A graceful, gilded dome soars overhead, catching the light and scattering it like soft ribbons across the shadowed interior. Every surface seems to glow — plaster columns wrapped in delicate patterns, exquisite reliefs that whisper stories in stone — each detail inviting you to linger and look closer.
I was especially captivated by the beautifully carved wooden doors, their deep tones glinting like burnished brass. Crafted around 1214 by the medieval Croatian sculptor and painter Andrija Buvina, these monumental doors stand among Croatia’s finest examples of Romanesque sculpture. Each door unfolds 14 scenes from the life of Christ, framed and separated by lavish, intricate patterns that draw the eye and invite lingering admiration.
On the sacristy’s ground floor lies a small treasury, where the relics of Saint Dominus — carefully brought to the cathedral after his passing — rest in quiet reverence.
Among its other treasures are revered sacred texts dating back to the 6th century, a graceful 13th-century Romanesque panel of the Madonna and Child, glittering chalices and ornate shrines crafted by goldsmiths between the 13th and 19th centuries and an array of sumptuous robes spanning the 14th to the 19th centuries.
The site was meant to be Emperor Diocletian’s grand mausoleum — his final resting place — but history had other plans. During his reign he drove Christians from nearby islands, killing some and persecuting many. After his death, those same believers returned to Split and laid hands on the emperor’s sarcophagus, removing it from the mausoleum and replacing its contents with the bones of Salona’s martyr and bishop, Saint Domnius. The building soon took on a new life as a cathedral, a quietly triumphant transformation that endures to this day.
Dedicated at the turn of the 7th century AD, the cathedral is often celebrated as the world’s oldest Catholic church still used in its original form — largely untouched by major later renovations. Its lone nod to a later era is the graceful bell tower added in the 12th century.
The structure itself — erected in AD 305 as the intended Mausoleum of Diocletian — remains the second-oldest building ever repurposed for use as a Christian cathedral.
08 | Ascend Saint Domnius Bell Tower
Rising 187 feet above the old city, the Saint Domnius Bell Tower began to take shape around 1100 AD — and some tellers of tales insist its construction stretched across three centuries. Though its bones are primarily Romanesque, the long building voyage left traces of other styles woven into its stonework. In 1908, the tower was carefully rebuilt and subtly reimagined, a restoration that sadly led to the loss of several original Romanesque sculptures but preserved the tower’s timeless silhouette.
Climbing the bell tower’s steep steps, you move mostly in soft, dim light. Slivers of sunlight slip through the few arched windows, each one like a little secret letting the outside in. With every window you pass, the city and sea unfold a bit more — gentle, widening views that reward the slow, upward climb — 178 worn stone steps to the top of the Saint Domnius Bell Tower.
Once you climb high enough, you can see past the terracotta roofs to the sea, where large boats and cruise ships bob gently. Sunlight shivers across the smooth water and trails like snail tracks lace the surface — tiny clues left behind. Looking down into Split’s streets, you notice just how dense the city is: narrow lanes etched between tall white buildings, their tiled rooftops flowing together like a meandering river.
I was utterly beguiled by the clockwork tucked inside the bell tower — a delicate forest of pulleys and ropes, clearly designed to coax the bell into song.
The descent turns out to be far gentler than you fear — if a touch dramatic. The stairs are narrow and startlingly steep, so you’ll find yourself stepping to the side for others as you pass but every careful step feels rewarded. Once you reach solid ground again, linger for a moment to catch your breath and savor the relief before moving on.
The five-tiered tower draws crowds for its unforgettable panoramas of Split and the scattered islands; take your time on the climb, steady yourself on the rail when you can and savor every view.
09 | Witness A Cappella Singing in the Vestibule
Continue drifting down the narrow lanes, where tiny boutiques spill over with local artwork and one-of-a-kind handcrafts. I came away with a bar of artisanal soap and a lovely metal camper’s mug, hand-painted with “Split” across the front — small treasures that instantly felt like souvenirs of the place.
Locate the Vestibule (Vestíbulo) — also called the Atrium or Rotunda — at the start of the Imperial corridor of Diocletian’s Palace, the passage that leads into the Peristyle. Once the stately gateway to the imperial apartments, the Vestibule greets you with a surprising geometry: a square exterior that gives way to a circular interior.
To its southeast, the medieval quarter unfurls, anchored by the city’s oldest dwelling, an early Romanesque house from the 10th century. On the opposite side stands the church of Saint Andrija, now absorbed into the charm of the Ethnographic Museum.
Erected with the rest of the ancient palace at the dawn of the 4th century, this space served as a grand ceremonial hall for special occasions. A gleaming dome of colorful mosaic tiles once crowned the circular room, soaring 55 feet high and stretching 40 feet across. The entrance was guarded by a great carved door and four semicircular niches — each cradling a statue of an enigmatic deity — lined the walls, adding an air of mystery to its splendor.
Now that the dome is gone, sunlight floods Diocletian’s Palace vestibule, setting the white stone aglow. The bright blue sky frames the space, heightening its monumentality and giving the room a light, airy grandeur. With its remarkable acoustics, the vestibule has found a new life hosting informal klapa performances — an entrancing, a cappella tradition from Dalmatia where multipart voices weave together in warm, unaccompanied harmony.
In summer’s glow, these a cappella troupes fill the Rotunda with beloved folk melodies, using the space’s perfect acoustics to weave voices into shimmering harmonies. Arranged in a welcoming semicircle, they perform for gathered crowds who offer donations as they wish. Today, their songs are cherished as part of UNESCO’s Intangible Cultural Heritage of Humanity.
As a delightful fusion of old-world traditions and contemporary flair, I was enchanted to witness one of these spellbinding performances during my visit to Split.
Entry to the palace’s private chambers is through the elegant Vestibule, a graceful threshold that hints at the treasures beyond.
10 | Explore Diocletian's Living Quarters
Once you pass through the Vestibule, the Emperor’s apartment gently reveals itself. Nestled along the palace’s southern seafront edge, it occupies a graceful block crowned by a domed, circular exterior. The suite runs an impressive 130 feet along the entire south façade. While the upper floor survives only in fragments, the ground level remains remarkably intact, offering a vivid sense of the space as it once was.
On the west side of the upper floor lie the gentle ruins of a domed hall and two niche-lined chambers, their echoes hinting at former grace. To the east, fragments of an octagonal dining room unfold alongside three cross‑shaped halls; the western arm of the cross still stands proudly at its full height.
Diocletian’s apartment was tied together by a sunlit gallery running along the southern side, its 42 windows and three balconies framing endless sea views. Recently, excavations also revealed two baths just to the north of the imperial quarters, adding a private touch of luxury to the residence. You can also savor mouthwatering views of the bell tower from a fresh, irresistible vantage point.
As I wandered through the space, I loved imagining the palace at its height — a living, breathing miniature city. Sunlight would have poured through colonnades and marble arcades, casting warm bands of light across mosaic floors polished by countless footsteps. Servants and officials moved in purposeful streams: bakers delivering morning bread from vaulted ovens, messengers weaving between courtyards with sealed scrolls and market stalls in the Peristyle offering fresh fish, fragrant herbs and glistening olives. The air carried a mix of scents — citrus from potted trees, rosemary and bay from kitchen gardens and the faint salt tang drifting in from the nearby sea.
Gardens bloomed in terraces and shaded atriums, their fountains providing a cool, rhythmic soundtrack as birds nested in orange trees and bees busied among flowering vines. Chickens clucked and pecked in tucked-away courtyards near service quarters, while more prized animals — geese, small dogs, perhaps even a tame peacock — paraded through grander spaces to delight guests.
Diocletian’s private quarters would have combined imperial dignity with domestic comfort. Imagine a suite of rooms opening off a secluded peristyle: sleeping chambers lined with richly woven textiles and bolstered couches, a private triclinium (formal dining room) where he dined with trusted advisers beneath painted ceilings and a study layered with scrolls and carved furniture. Water basins and small baths sat close at hand for cooling rituals; discreet service passages ensured attendants moved unseen, refilling lamps, replenishing oil for the braziers (metal heating and cooking device) and bringing delicate dishes of spiced fish, figs and honeyed cakes.
Ceremonial life threaded through daily routines — the emperor’s visible presence at key hours, receiving petitions in an audience hall, performing rites that reinforced his authority. Yet the palace also thrummed with ordinary details: laundresses beating linens in hidden yards, children playing chase along shaded colonnades and the distant clang of smiths and carpenters maintaining the infrastructure of a self-contained imperial compound. In that vision, the stone walls of the palace cease to be silent ruins and instead ring with the layered sounds, colors and small domestic dramas of a vibrant court.
11 | Grab a Bite at Fig Split — If You Dare
In the late afternoon, after many hours of exploring, grab a bite at Fig Split (or don’t).
Happy to be off my exhausted feet, I sat in their sun soaked courtyard and ordered up a storm. With a fresh and creative take on local ingredients, Fig Split offers some interesting dishes. To drink, I chose a virgin cherry spritz and for my meal, roasted veggies with sweet potatoes, leeks, fennel, carrots and beets served on house made white bean hummus with lemon and lamb’s lettuce.
As if that wasn’t enough, I chose the chimichurri potatoes, smashed and fried red potatoes served with vegan chimichurri mayo.
Overall, the food was quite enjoyable, though the service left a bit to be desired. Unfortunately, I got very sick about an hour later — food poisoning, sadly. Fingers crossed it was a one-off but it’s wise to be cautious if you dine here.
Tip | Dine at Fig Split with caution — I came away with a bout of food poisoning.
Because I came down with a vicious bout of food poisoning, I had to bow out of my Blue Caves tour the following day — but luckily I persuaded the kind gentleman to let me join the following day. Relief! After a sun-soaked, wind-whipped day of island hopping, I packed my suitcases and met my group and guide at the taxi station for a day trip to Plitviče Lakes National Park in central Croatia. Planning to stay the night at the lakes instead of returning to Split, I hauled all my belongings along.
And after that round of food poisoning, I realized I’m done with crowded hostel dorms — from now on, I’ll be flying solo and loving my own little corner of the world!
