Cardiff Castle

Stand still for a moment on the wide green lawn inside the walls. The grass is soft underfoot, and the traffic of the city centre fades to a low hum behind the stone. Above you, a round grey keep sits on its steep mound. Across the lawn, a tall tower of golden stone rises, covered in carved figures and painted shields. Between them lies nearly two thousand years of change, all inside one set of walls.

This is Cardiff Castle. It is one of the few places where you can see three very different worlds side by side. There is a Roman fort, a Norman stronghold, and a Victorian dream palace. Most castles show one great age. This one shows many. As you walk, try to notice where one age stops and the next begins. The walls themselves will help you.

Start with the Romans. Soldiers of the Roman Empire built a fort on this spot. The site sat close to the River Taff and near the sea, so it made sense for control of the coast. The fort was rebuilt more than once over the centuries of Roman rule in Britain. Later builders reused its lines, and that is why the castle walls form such a neat rectangle today.

Here is the first detail many visitors walk past. Look at the lower part of the outer walls. In places you will see a band of reddish stone running along the masonry. That band marks the line of the original Roman wall. Everything below it is Roman work, uncovered in the early twentieth century. Everything above it was rebuilt later. So when you touch the base of these walls, you may be touching stone laid by Roman hands.

Now turn to the mound in the corner of the lawn. After the Norman Conquest of England, the new Norman lords pushed into South Wales. In the late eleventh century they raised this earth mound, called a motte, inside the old Roman walls. At first a timber tower stood on top. Later it was replaced by the stone shell keep you see now. A shell keep is a ring of stone wall around the top of a mound, rather than a solid square tower.

This keep holds a darker story. Robert, known as Robert Curthose, was the eldest son of William the Conqueror. He lost a struggle for power against his younger brother, King Henry the First. Robert spent many years as a prisoner, and he was held for a time here at Cardiff. He died in captivity in 1134. Think about that as you climb the steps... a king's son, shut away for decades in a corner of Wales.

The climb to the keep is steep, but the reward is worth it. From the top, you can see across the whole castle site. You can see the green treetops of the park to the north and the roofs of the city to the south. On a clear day the light moves fast over the stone as clouds cross. This is the best place to understand the shape of the fort. The rectangle of walls is easy to read from up here.

For several centuries after the Middle Ages, the castle passed through the hands of different noble families. It was repaired, changed, and sometimes neglected. Then, in the nineteenth century, it came to the Bute family. Their timing was perfect. South Wales was producing huge amounts of coal, and Cardiff grew into one of the busiest coal ports in the world. The Butes owned land and docks, and the coal trade made them extremely rich.

The third Marquess of Bute was a scholar with a deep love of the Middle Ages. He hired an architect named William Burges, a man with an equal passion for medieval fantasy. Together, from the 1860s onwards, they turned the old lodgings into a Gothic Revival palace. Gothic Revival was a Victorian style that copied and reimagined the churches and castles of the Middle Ages. Here, they took that idea further than almost anyone else in Britain.

The Clock Tower is the clearest sign of their ambition. Look up at it from the lawn. You will see carved figures, bright heraldic shields, and rich gilding. The tower was not built for defence. It held private rooms for the Marquess, decorated with themes of time, the seasons, and the planets. Inside the house, rooms like the Banqueting Hall and the Arab Room are covered in painted wood, gold leaf, and carved detail from floor to ceiling.

Here is a second surprise. The walls of this castle also served in the Second World War. During the air raids on Cardiff, long tunnels inside the thick walls became shelters for local people. Thousands could crowd into them when the sirens sounded. Today you can walk through these passages. They are cool, dim, and narrow, and some displays recall what those nights felt like for families from nearby streets.

In 1947, the Bute family gave the castle and much of the land around it to the people of Cardiff. That gift is why the city has such a large green space at its heart. Behind the castle walls lies Bute Park, with wide lawns, old trees, and paths along the river. Many locals cross it every day on their way to work. The castle is not cut off from city life. It sits right in the middle of it.

Before you leave, walk out to the street along the castle's western side. Look along the wall that runs beside the road. Stone animals peer over the top of it. There are lions, bears, a hyena, and many others. This is the Animal Wall, designed by William Burges, with more creatures added later. Children love to count them, and many adults do too. Their glass eyes and sharp claws make them feel almost alive.

So take one last look around you. The red line of Roman stone at the base. The grey Norman keep on its mound. The gilded Victorian tower catching the light. Three ages, one site, and a city that grew up around them all. As you walk back into the noise of the streets, glance up at those stone animals once more. They have watched this corner of Cardiff for well over a century.
