Chepstow Castle

Listen first. Below the walls, the River Wye runs brown and fast between steep limestone banks. When the tide is out, wide slopes of grey mud shine in the light. When it returns, the water rises quickly, and the sound of the river changes. Under your feet are worn stone and short grass. Above you, a long line of walls follows the edge of the cliff. This is Chepstow Castle, and you are standing at one of the oldest stone fortresses in Britain.

The castle sits on a narrow ridge. On one side is a sheer drop to the river. On the other side, the ground falls away into a small valley. The builders used this shape well. They made the castle long and thin, like a ship on a rock. That is why you walk through it in a line, from one enclosure to the next. Each courtyard is called a bailey, an enclosed yard inside the walls. Each bailey was a further barrier for an attacker.

The story begins very soon after 1066, the year the Normans, the French-speaking warriors from northern France, conquered England. William the Conqueror gave this border country to one of his closest allies, William FitzOsbern. FitzOsbern started work here within a year or two of the conquest. Most early Norman castles were built from earth and timber. This one was built in stone from the start. That choice tells you something. The Normans meant to stay, and they wanted everyone across the river to see it.

The river matters. The Wye marks part of the border between England and Wales. Here at Chepstow, it also gave the castle a route to the sea. Boats could come up from the Severn Estuary to supply the garrison. The Severn has one of the largest tidal ranges in the world, and the Wye feels that tide here. So the castle could receive food and soldiers by water — a large advantage on a hostile frontier.

At the centre of the ridge stands the Great Tower. This is FitzOsbern's original building, and it is the heart of the castle. It was not mainly a place for battle. It was a grand hall, a place for ceremony and power. Look at the lower walls closely. You may see thin red bands of brick and tile among the pale stone. Historians believe much of this material was taken from Roman ruins nearby, probably the old Roman town at Caerwent. So a Norman lord built his hall partly with Roman pieces.

After FitzOsbern, the castle passed through several powerful families. The most famous owner was William Marshal. Writers of his own time described him as one of the finest knights in Europe. He served several English kings, and he became one of the most trusted men in the kingdom. Around 1200, Marshal began to modernise Chepstow. He added new walls and strong round towers. Round towers were harder to undermine than square ones, and archers could cover more ground from them.

Now here is a detail most visitors walk past. The castle's great wooden gates once hung in the main gatehouse. Scientists dated the timber by studying the growth rings in the wood. The results show the doors were made before 1190. That makes them the oldest known castle doors in Europe. They stood in the entrance for centuries. Today they are kept indoors to protect them, and you can see them inside the castle. They are thick oak, covered with iron plates.

Marshal's sons continued his work. They strengthened the western end and built the barbican, an outer defensive gateway in front of the main walls. They also added more space to the Great Tower. As you walk from end to end, you are walking through about two centuries of building. The stone colour changes. The window shapes change. The way the walls meet the rock changes. Each generation added its own layer, and the joins are still visible.

Later in the thirteenth century, the castle came to Roger Bigod, the Earl of Norfolk. He was very rich, and he wanted comfort as well as strength. In the lower bailey he built fine domestic buildings, with a hall, kitchens, and private rooms. They sit right above the cliff. Look for the large windows facing the river. He also built the big tower near the main gate. Here, the castle became a home as well as a fortress.

That tower has a second story. It is called Marten's Tower, after Henry Marten. Marten was one of the men who signed the death warrant of King Charles the First in 1649. When the monarchy returned, the new government punished many of those men. Marten escaped execution. Instead, he was held at Chepstow for many years. He died here in 1680. A tower built for a medieval earl became the home of a political prisoner.

The castle also saw real fighting. During the English Civil War in the 1640s, King and Parliament fought for control of the country. Chepstow was besieged twice. In the second siege, in 1648, Parliament's guns broke the walls. The royalist commander, Sir Nicholas Kemeys, was killed. Some scars from that time remain. After the war, the castle was kept as a garrison for a while. Later its military role faded, and slowly it became a ruin.

Today, the Welsh heritage body Cadw looks after the site. Wales has its own national system for protecting historic places. Most rooms are open to the sky now. Floors have gone, so you can look straight up through several storeys. You can see fireplaces hanging high on the walls. You can see holes where large beams once rested. Try to rebuild the rooms in your mind. Imagine the smoke, the noise, the crowded stairs, and the cold air coming off the river.

Before you leave, stand by the walls above the Wye. Look across to the English bank, only a short distance away. For centuries, this narrow strip of water felt like a frontier. Now listen again. You may hear birds, the traffic on the old bridge, or the tide moving past the rock. The same river shaped every choice the builders made... And as you walk back through the gate, notice how small the entrance feels, after all this stone.
