Article Summary
Cardiff Castle is a historic fortress and Gothic Revival mansion in the heart of the Welsh capital, spanning nearly 2,000 years of history from Roman times to the Victorian era. This guide covers the castle’s remarkable history, its lavish Victorian interiors created for the Marquess of Bute, and practical information for planning your visit including what to see, tour options, and tips for making the most of this unmissable Welsh attraction.
A Castle at the Heart of Wales
Cardiff Castle stands in the centre of the Welsh capital, its medieval walls and fairy-tale towers rising above the busy streets of a modern city. For nearly two millennia, this site has been a place of power, defence, and display—from Roman garrison to Norman stronghold to Victorian fantasy. Today it ranks among the most visited attractions in Wales, drawing visitors who come to explore its layered history and marvel at some of the most extravagant interiors in Britain.
What makes Cardiff Castle exceptional is the way it condenses so much history into a single site. Within these walls you can walk on Roman foundations, climb a Norman keep, and wander through apartments decorated with such opulence that they would make a Renaissance prince blush. Few places in Britain offer such a vivid journey through time, and fewer still do so in the heart of a thriving capital city.
The Roman Fortress
The story of Cardiff Castle begins with the Romans, who established a fort here around 55 AD during their conquest of Wales. The location was strategic—a crossing point on the River Taff, close to the Bristol Channel, and positioned to control movement along the south Wales coastal plain.
The Romans built and rebuilt their fortifications here over the following three centuries. The walls you see today along the southern and western sides of the castle grounds follow the lines of the Roman defences, reconstructed in the Victorian period but standing on original foundations. Archaeological excavations have revealed the remains of Roman gateways, barracks, and other structures beneath the castle grounds.
By the late third century, the Romans had constructed a substantial stone fort here, part of a chain of coastal defences against seaborne raiders. When the legions withdrew from Britain in the early fifth century, they left behind walls that would shape the site’s development for the next 1,500 years.
The Norman Conquest and Medieval Castle
The Normans arrived in south Wales in the 1080s, and William the Conqueror himself may have visited the site of Cardiff Castle in 1081. The Norman lord Robert Fitzhamon established a new fortress here around 1091, using the old Roman walls as the outer defences and raising a great motte—an artificial mound—in one corner of the enclosure.
The motte at Cardiff Castle remains one of the finest examples in Wales. Topped by a twelve-sided stone shell keep built in the twelfth century, it dominates the castle grounds and offers commanding views across the city. Climbing the steep steps to the keep is one of the highlights of any visit, rewarding the effort with panoramic views and a tangible connection to the medieval past.
Through the medieval period, Cardiff Castle served as the administrative centre of the Lordship of Glamorgan. It passed through various hands—the de Clare family, the Despensers, the Beauchamps, the Nevilles—as fortunes rose and fell in the turbulent politics of medieval Wales and England. The castle was besieged, captured, and rebuilt multiple times.
The Black Tower and the octagonal tower that flanks the main entrance date from this medieval period, though both were substantially altered in later centuries. The medieval domestic ranges that once stood within the walls have largely disappeared, replaced by the Victorian mansion that now dominates the site.
The Herbert and Stuart Periods
By the Tudor period, Cardiff Castle had passed to the Herbert family, who would hold it for over two centuries. The castle’s military importance declined as Wales was integrated more fully into the English state, and the Herberts gradually transformed the fortress into a more comfortable residence.
The Civil War brought a final burst of military activity. Cardiff Castle was held for the King, besieged by Parliamentary forces, and eventually surrendered in 1645. The conflict left the castle damaged, and the Herberts undertook repairs and improvements through the later seventeenth century.
In 1766, the castle passed by marriage to John Stuart, Lord Mountstuart, who would become the first Marquess of Bute. This Scottish aristocratic family would transform Cardiff Castle—and the city of Cardiff itself—beyond recognition.
The Bute Family and the Transformation of Cardiff
The Bute family’s influence on Cardiff cannot be overstated. They developed the docks that made Cardiff one of the world’s great coal-exporting ports, and the wealth that flowed from that trade funded an extraordinary programme of building and patronage.
The first Marquess began improvements to the castle, engaging the architect Henry Holland and the landscape designer Capability Brown to modernise the buildings and grounds. But it was the second and third Marquesses who would create the Cardiff Castle we see today.
John Crichton-Stuart, the second Marquess of Bute, was reputed to be the richest man in the world at his death in 1848. He continued the development of the docks and began transforming the castle’s medieval apartments into something grander. His son, the third Marquess, would take this transformation to extraordinary lengths.
William Burges and the Victorian Fantasy
The third Marquess of Bute inherited his title at just six months old, along with a fortune that made him one of the wealthiest men in Victorian Britain. He was also brilliant, eccentric, deeply religious—he converted to Catholicism—and passionate about history, architecture, and the Middle Ages.
In 1865, the young Marquess met the architect William Burges, and the two men discovered a shared obsession with medieval art and Gothic architecture. Their collaboration at Cardiff Castle, which continued until Burges’s death in 1881, produced one of the most remarkable interiors in Britain.
Burges transformed the castle’s western apartments into a Gothic fantasy of astonishing richness. Every surface is decorated—carved, painted, gilded, or inlaid with precious materials. The effect is overwhelming, a total work of art that draws on medieval manuscripts, Islamic design, classical mythology, and Victorian romanticism.
The Clock Tower, completed in 1873, contains a bachelor bedroom, a winter smoking room, and a summer smoking room stacked vertically and connected by a spiral stair. Each room pursues its theme with obsessive detail. The winter smoking room features a chimneypiece depicting the tale of Chaucer’s Pardoner, while the summer smoking room is decorated with scenes of love and courtship.
The Banqueting Hall, the Library, the Arab Room, and the Chaucer Room each offer their own visual feast. Burges designed everything—furniture, light fittings, door handles, fireplace tools—to create unified environments of extraordinary intensity. Whether you find the results magnificent or excessive (or both), they are unforgettable.
The Castle in the Twentieth Century
The Bute family’s connection with Cardiff weakened through the twentieth century. The coal trade declined, the docks fell quiet, and the family’s centre of gravity shifted elsewhere. In 1947, the fifth Marquess of Bute gave Cardiff Castle to the city, along with the surrounding parkland that now forms Bute Park.
The castle has been in public ownership ever since, managed first by Cardiff City Council and now by Cardiff Council. Extensive restoration work has preserved and revealed the Victorian interiors, while archaeological investigations have deepened understanding of the castle’s earlier phases.
Today Cardiff Castle hosts events ranging from concerts in the grounds to medieval banquets in the state apartments. The castle grounds, open to the public free of charge, serve as a green lung in the city centre, a place where office workers eat lunch and tourists photograph the peacocks that strut across the lawns.
What to See at Cardiff Castle
The Castle Apartments
The Victorian apartments created by Burges for the third Marquess of Bute are the castle’s unmissable highlight. Access is by guided tour, included with some ticket types or available as an upgrade. The tour takes visitors through the sequence of rooms—the Library, the Banqueting Hall, the Arab Room, the Nursery, and others—with guides explaining the symbolism and craftsmanship of each space.
Allow at least an hour for the house tour, longer if you want to absorb the detail. Photography is permitted, though the richness of the interiors is difficult to capture. Every visit reveals something new—a carved mouse in a corner, a hidden face in the tilework, a joke in Latin inscribed above a door.
The Norman Keep
The twelfth-century shell keep on its Norman motte offers the castle’s best views and a powerful sense of medieval history. The climb is steep—approximately 50 steps up the motte and more within the keep itself—but the reward is a panorama across Cardiff, from the city centre to Cardiff Bay, the Bristol Channel, and the hills beyond.
Inside the keep, interpretation panels explain the castle’s Norman history. The walls themselves are atmospheric, weathered stone enclosing an open courtyard where defenders once gathered.
The Castle Walls and Battlements
A wall walk allows visitors to explore the castle’s defences, passing through towers and along battlements with views into the castle grounds and out across the city. The walk includes displays on the castle’s military history and the various phases of construction.
The Wartime Tunnels
During the Second World War, tunnels within the castle walls served as air raid shelters, protecting thousands of Cardiff residents during bombing raids. These tunnels have been restored and opened to visitors, with displays recreating the wartime experience including sound effects and period furnishings.
The Grounds and Interpretation Centre
The castle grounds include the Firing Line museum, dedicated to the military history of Wales and the Welsh soldier. The interpretation centre provides context for the castle’s long history, with models, timelines, and archaeological finds.
The grounds themselves reward exploration, from the Animal Wall along Castle Street (featuring carved stone animals designed by Burges) to the peacocks wandering the lawns and the views back to the Gothic towers.
