My Bibimbap Moment

This trip added: Imagination.

Cardiff Castle added the ingredient of imagination to my Bibimbap Life. Every part of the castle seemed to open onto a different world. The ornate apartments were filled with intricate carvings, stained glass and details that made it easy to imagine the lives once lived there. Outside, the castle itself felt wonderfully different — rustic, sturdy and quietly imposing, rising above the green grounds at the center of the city.

Then came the wartime tunnels, damp and eerie, with recorded evacuation warnings echoing through the space. For a few hours, I moved between centuries of history, from medieval stone to Victorian grandeur and the unsettling reminders of war. Even the rain that finally sent me away felt like part of the atmosphere.

Two-Week Travel Itinerary

My two-week journey through Europe unfolded as a mix of city streets, island escapes, historic towns and Mediterranean sunshine. Cardiff was one stop along the way — a memorable chapter in a trip that carried me from the familiar energy of London to Wales, the Channel Islands, France and eventually the French Riviera.

The journey began in the capital of England, London, where I spent time wandering familiar neighborhoods, lingering over coffee and soaking up the city's endless energy. From there, I took the train west to Wales. Cardiff quickly won me over with its walkable streets, historic arcades, comforting food and rainy-day charm. Cardiff Castle became one of the highlights of my time there, its grand walls and centuries of history rising unexpectedly in the middle of the city. I later continued to the colorful seaside town of Tenby, where pastel houses, narrow streets and long stretches of beach offered an entirely different pace.

After returning briefly to London, I crossed the Channel to Jersey. The island brought another shift in scenery, with charming coastal villages, fresh seafood, historic sites and quiet moments by the sea. From there, a ferry carried me to France, with an unexpected overnight stay in Saint-Malo becoming one of the journey's happiest surprises. Its walled old town and dramatic coastline made the brief detour feel like a destination in its own right.

Next came Nantes, a city that completely exceeded my expectations. Its historic streets and grand architecture sat alongside whimsical art and one of the most fascinating attractions I've ever visited, making it a place that felt both rooted in the past and wonderfully imaginative.

For the final stretch, I headed south to the French Riviera. Nice brought sunshine, Mediterranean charm, colorful markets and long walks by the sea. Nearby Monaco revealed a side I hadn't expected either — one shaped as much by historic streets, gardens, food and maritime history as by its more famous image.

Looking back, the trip feels like a collection of wonderfully different places connected by trains, ferries and a willingness to keep going somewhere new. From rainy walks through Cardiff to island coastlines and sunlit Mediterranean streets, each stop added something different to the journey — and together, they became a trip I still think about often.

Cardiff Castle Beckons: Exploring Cardiff UK & Its Grand Centerpiece

Nestled in the vibrant heart of Cardiff, UK, Cardiff Castle stands as a spellbinding centerpiece where 2,000 years of history meet lush Victorian-era gardens and soaring Gothic revival towers, inviting visitors to wander through Roman walls, a Norman keep and lavishly decorated state rooms that glitter with intricate plasterwork and medieval-inspired murals.

Beyond the castle’s dramatic battlements, the city of Cardiff, Wales unfolds with a lively waterfront, cozy cafes and cultural gems, making a short stroll from the castle’s park enough to sample local cuisine, modern art and warm Welsh hospitality — all framing a perfect day of exploration centered on one unforgettable fortress.

Discover Cardiff Castle & Firing Line Museum — Charm, History & Cardiff UK Explored

Carved in the heart of Cardiff’s city center, Cardiff Castle sits like a storybook come to life, surrounded by sweeping parkland that invites you to pause and wander. Its Romanesque walls and whimsical towers whisper of 2,000 years of history — from a 1st-century Roman fort to the Norman stronghold founded after William the Conqueror’s arrival. Parts of that ancient fort were even lovingly reconstructed in the 20th century, weaving old stones and modern restoration into the castle’s fabric.

Open every day of the year, Cardiff Castle welcomes wanderers with free access to its sweeping grounds — though if you want to step fully into history and explore its inner treasures, a ticket at the Visitor Centre gets you inside. Start there, pick up your ticket, then head downstairs to the Firing Line Museum, where the stories of The Queen’s Dragoon Guards and The Royal Welsh unfold across a rich collection of exhibits and artifacts. Then, move on to explore the inner grounds.

Once you pass through the gate, the castle becomes a playground for curious minds. Scale the stout Norman Keep for panoramic views that put the surrounding city in miniature. Pause by the life-size replica medieval trebuchet — a theatrical reminder of siegecraft that I somehow managed to miss on my visit. Wander through the sumptuous Castle Apartments, once home to one of the wealthiest men in the world; the lavish rooms feel like sets from a period drama.

Outside the castle, history keeps revealing itself in unexpected corners where Roman remains whisper of ancient roots: the charmingly named Chariot Corner and the stark Wartime Shelters that tell quieter, grittier stories. When you’re ready to breathe, follow the Battlement Walks for sweeping vistas or drift into nearby Bute Park for a gentle, leafy lullaby — perfect places to let the castle’s echoes settle into your day.

Uncover the Charming Castle Apartments of Cardiff UK

The Victorian Apartments at Cardiff Castle are residential wings with beginnings that reach back to the 1400s but centuries of additions and reinvention have given them a layered, storybook quality.

By the 1580s, when the Earls of Pembroke could finally trade constant vigilance for creature comforts, they set about turning the castle into a lavish home. Time and tastes tugged the place in new directions and by 1766, when the Bute family took over, parts of the house had slipped into neglect. Lord Bute brought in architect Henry Holland and his father-in-law to tear down, rebuild and reimagine.

The real magic began in 1865, when the 3rd Marquess of Bute teamed up with William Burges, an artist-architect whose imagination seemed to dwell in a romantic past. The pair, both fascinated by medieval grandeur, set out to craft a fantasy palace, sparing no expense.

Walking through the apartments today feels like stepping into one of their dreams: a gothic feast of opulent murals, gilded surfaces that catch the light, painstaking wood carvings, jewel-toned stained glass and smooth, pale marble. Every corner whispers of obsession with history, turned into breathtaking, theatrical beauty.

Lord Bute’s study still holds the silence of mapped plans and quiet contemplation, while the Guest Tower promises secrets and surprise views from its narrow windows. Each room has a personality: the Arab Room with its exotic flair, the cosy Nursery and the grand Banqueting Hall where echoes of laughter must still linger. The Dining Room, Drawing Room and Library invite slow conversation and page-turning afternoons and the bedrooms for Lady and Lord Bute are intimate, quietly elegant retreats.

The Banqueting Hall is the jewel of the house — the largest chamber, sitting in the oldest part of the castle. Its bones reach back to the 15th century but the walls have been dressed in Victorian finery: a tapestry of surface designs, ornate ceiling work and polished floors that marry medieval strength with Victorian glamour. Standing there, you can feel centuries layered on top of one another, each era leaving its own beautiful mark.

My favorite was the Arab Room — one of William Burges’s last creations, completed in 1881, the year he died. Step beneath its ceiling and you understand why people pause here: a muqarnas canopy, shimmering like carved honeycomb, folds overhead. The word muqarnas — “horn” or “ridge” — hints at the many tiny, ornamental nodules that catch the light and draw the eye into ever-smaller, perfectly arranged shapes.

Unlike the stone and plaster versions seen in mosques and madrasas, this muqarnas is crafted from wood, each surface painted and gilded with gold leaf. Up close, the detail feels almost impossible: miniature vaults within vaults, a three-dimensional geometry somehow playful and solemn at once. In a quiet room filled with history, that ceiling is the kind of thing that makes you stop, tilt your head and breathe it all in.

The shapes are mesmerizing, like a gentle optical illusion that invites the eye to wander. Sunlight and shadow dance across the room in slow choreography, turning every corner into a small revelation. The space carries a quiet, almost spiritual hush that feels both calming and uplifting. I was also very much taken with the large stained-glass windows — jewel-toned panels that pour rich, saturated color into the room and make everything glow with a kind of reverent warmth.

Summit the Norman Keep at Cardiff Castle

A cool, crisp breeze nudges toward the castle, sending a quiet invitation. What secrets wait behind those storied stone walls and what views would be revealed from the tower — rolling fields, a maze of tiny rooftops, a river glinting in the distance?

The grounds are a classic motte-and-bailey: two simple yet beguiling parts. The motte is the raised mound — often shaped by human hands — crowned with a keep, its silhouette bold against the sky. Below, the bailey spreads out: an enclosed courtyard that once hummed with daily life.

Imagine narrow lanes of timbered houses, kitchens sending up constant smoke, chapels chiming and stores and workshops busy with trade. The bailey was the castle’s beating heart, a small village within walls where people lived, worked and kept the stronghold running. Standing there, it’s easy to picture the past folding into the present, each stone holding a story waiting to be discovered.

The very first Roman fort in Cardiff UK was likely established at the end of the 50’s AD on a strategic site that offered easy access to the sea. Its original intention was presumably to aid in subduing the local tribe know as the Silures. Archaeological excavations indicate that a series of four forts, each a different size, occupied the present site at different times.

The last fort was hewn from stone, its sturdy Roman walls rising as a quiet testimony to another age. Time and tides may have emptied the garrison after Rome’s decline but life lingered nearby. The little settlement that grew up beside the river kept the memory alive — its name, Caer-Taff, still whispers “fort on the Taff,” a small, enduring link between past and present.

After the Norman conquest, a new keep rose where a Roman fort once stood, as if layering centuries of stories in stone. Robert FitzHamon, the Norman lord of Gloucester, first crowned the motte with a timber stronghold — likely a wooden tower that marked the beginning of the site’s medieval rebirth.

Over the centuries, the castle grew like a tall tale — new medieval walls and cozy dwellings added bit by bit, each layer of stone whispering stories of the families who lived within. In 1766, a marriage handed the keys to the Bute family and their mark would be felt far beyond the castle gates. John Crichton-Stuart, the 2nd Marquess of Bute, helped transform nearby Cardiff into a powerhouse of coal export, turning a sleepy port into a global hub.

His son, John, the 3rd Marquess, inherited both the castle and the family fortune — and by the 1860s was said to be the richest man in the world. Standing beneath those ancient ramparts today, it’s easy to imagine the echoes of ambition and industry that reshaped a region and left such an improbably grand legacy.

Standing atop the most recognizable feature of Cardiff Castle — its striking twelve-sided Keep — it feels as if the city unfolds beneath you like a well worn map. From that lofty viewpoint, the whole courtyard reveals itself and beyond it, the pulse of Cardiff stretches toward the horizon.

This Keep, the finest example of its kind in Wales, is a classic “shell” Keep: a robust stone shell forming a protective embrace around the smaller buildings once nested inside. Imagine early 12th-century masons, under the watch of Robert Consul, Earl of Gloucester, replacing the old timber defenses with this resolute stone heart. The walls seem to hold memories of long-ago life — and darker chapters too. For eight years the Keep doubled as a prison for Duke Robert of Normandy, the eldest son of William the Conqueror, who died here in 1134 at the age of eighty.

The Keep rises atop an artificial motte more than 35 feet (10 meters) high, its summit stretching over 100 feet (30 meters) across like a natural little kingdom. From the very top, the views unfold endlessly — a sweeping panorama that, on a clear day, reaches north to the fairytale silhouette of Castell Coch, that 19th‑century Gothic Revival dream perched above the village of Tongwynlais.

Additions in the 13th and 14th centuries gave the place a touch of medieval drama: a gatehouse rose beside the moat, its stone staircase winding up to a sturdy stone bridge that took the place of the old timber drawbridge. Imagine crossing that bridge centuries ago, the water sparkling below and the gatehouse looming above. Time, however, has its own plans — the gatehouse itself was taken down in the 18th century, leaving only the story and the stones to whisper of its once-grand entrance.

Some of the loveliest views open onto a small circular courtyard eased behind the Keep. Its lines are unexpectedly spare compared with the rest of the castle — a calm, pared-back heart among the stone grandeur. Green shoots push up between the flagstones and in that quiet, sunlit pocket the place feels peaceful, as if the castle itself is taking a breath.

A short climb of roughly 50 steep stone steps leads to the Keep’s entrance and a few more await you if you want to reach the viewing platform. The ascent is a little breath-stealing but every heave and pause is rewarded — once you stand atop the castle, the world expands beneath you in a way that makes the effort feel part of the adventure.

Even after nearly a thousand years, the Keep still steals the show — a silent, towering presence that dominates the landscape and feels certain to stand proud for at least another thousand.

Inside, don’t miss the keeps quirky decorative touches — heraldic motifs, carved stone grotesques and a surprisingly intimate spiral stair — a reminder that this is as much a storyteller’s stage as it is a fortress; lingering there at dusk, when the light softens the masonry and the city hums below, you’re left with the pleasing sense that the keep doesn’t just guard Cardiff’s past — it invites you to imagine its many lives.

Experience Cardiff Castle Wartime Air Raid Shelters

Hidden within the castle’s medieval ramparts lies a secret that feels plucked from a fable: a network of tunnels. Their gentle calm and cool stone tell of a different era — World War II — when these passages became refuge. When air-raid sirens split the sky, up to 1,800 city residents would hurry into eight separate sections of the walls, finding shelter from the chaos above.

Imagine the scramble, softened by purpose-built ramps that let people flow down into safety with surprising ease. Inside, the walls held entire miniature communities: dormitory bunks for sleeping, tucked-away kitchens filling the air with comforting scents, discreet toilets and even first-aid posts ready to tend the wounded. Walking there today, you can still sense how ordinary life was quietly preserved inside ancient stone.

The castle even played a role in wartime ingenuity: its ramparts once anchored massive barrage balloons that floated above the city like silent, watchful guardians. These unmanned, tethered giants were deployed to shield streets and buildings from aerial attack, their gentle silhouettes a striking — if unexpected — addition to the historic skyline.

Today the tunnels feel like stepping into a war torn memory. As I wandered their narrow corridors, booming speakers overtook the air with wartime announcements — urgent, clipped warnings that once guided frightened crowds — interrupted every few minutes by piercing sirens.

Weathered posters lined the walls, offering curt advice on how to act during a gas attack or what a mealtime routine might look like. Add the cool, damp air and the tunnel’s soft, dim glow and the whole scene was equal parts haunting and humbling — an intimate, unsettling reminder of the lives that once moved through these very passages.

Wander the Roman Chariot Corner: Where Ancient Stones Meet Timeless Stories

Tucked beneath the south-east tower of Cardiff Castle, the Roman Chariot Corner is a captivating mural by Frank Abraham, commissioned by Cardiff City Council and completed between 1981 and 1983. Built from cement and plaster and finished in metallic gold paint, the mural’s finely rendered chariots, horses and figures sweep across the stone in vivid scenes that evoke the drama of early first-century Roman processions and invasions.

The artwork depicts the local Silurian village life and the Silures watching the invading Roman fleet approach, with men working in an armory and the tribe gathering to defend their land; visitors can admire the intricate brushwork and subtle weathering that lend the piece a timeless charm — a hidden gem that brings a touch of Roman splendor to the castle’s medieval walls.

Stroll Along The Battlement Walks

Rounding out a visit to Cardiff Castle before the skies open, take a leisurely stroll along the Battlement Walk toward the north gate. The path traces three sides of the castle’s outer defenses — beginning at the south wall, curving around the east and finishing at the north gate — offering a nice mix of views and history. Imagine Roman legionaries once pacing these very ramparts, keeping vigilant watch over the settlement below.

Cardiff’s Roman story has a lovely twist: it lay hidden for centuries until 1888, when Lord Bute’s workmen, removing Norman earthworks to make way for a new tower, stumbled upon ancient masonry. As excavations continued, the Roman walls revealed themselves and the 3rd Marquess made the surprising decision to abandon his tower plans and restore the fort instead.

Work resumed in 1897 on top of the original Roman foundations, a project that reached completion under the 4th Marquess in 1923. Today, the Battlement Walk lets you literally tread the layers of history — Roman stones beneath Victorian ambitions — while you take in the castle’s commanding views.

❤️ Best Memory: Discovering the site’s hidden corners

🎒 Take With You: Some places hold so many stories that a few hours can feel like stepping briefly into another world.

When I think back on Cardiff Castle, I remember how many different feelings could exist within one place. There was the beauty of the apartments, the solidity of the castle walls, the peaceful views over the city and then the sudden unease of standing in the dark tunnels as wartime warnings played overhead. Each space seemed to belong to a different chapter of the castle's story. I only spent a few hours there but it felt like much longer. By the time the rain finally pushed me out, I had fallen completely under its spell.

The Essentials

Cardiff Castle is a compact treasure trove, so knowing a few essentials beforehand makes the visit smoother and richer: buy tickets in advance for guided tours, wear comfortable shoes for cobbled courtyards and steep towers and allow 2–3 hours to savor the Norman keep, opulent Victorian apartments and the wartime tunnels.

It’s easy to reach — walk 10–15 minutes from Cardiff Central or Queen Street stations or take frequent buses into the city center — so plan a morning or late-afternoon visit to avoid peak crowds and catch softer light for photos.

Don’t miss the Norman motte and keep for panoramic city views, the Arab Room and Clock Tower for lavish Victorian decoration and the wartime tunnels for a glimpse into 20th-century history; the surrounding Bute Park is perfect for a picnic afterward.

Practical tips: check opening times seasonally, book special exhibitions in advance, bring a light layer (the castle can be breezy on exposed terraces) and consider combining your trip with the nearby National Museum, historic Arcades or Cardiff Bay for a full day of history and culture.
