Abergavenny Castle | Visit Welsh Castles
Hello Castle Crawlers, welcome to the first castle blog! It’s about Abergavenny Castle, a ruined Norman fortress in Monmouthshire, South Wales. Let’s get to it!
It was first built in 1087 by the Norman lord Hamelin de Balun to secure the borderlands after the Norman conquest of England. Right above the River Usk, the castle played a strategic role in controlling movement through the valley and maintaining power over the local Welsh population.
Only mere fragments of its former defences remain. But its long history of conflict, rebellion, and rebuilding reflects the complex relationship between the Normans and the native Welsh during the medieval period. The castle grounds now house a museum and offer views across the castle and the surrounding hills.
Quick Facts
Date of construction: Around 1087
Location: Abergavenny, Monmouthshire, South Wales
Who built it: Hamelin de Balun, a Norman baron
Key purpose: Military stronghold to control the Welsh Marches
A Brief History
The castle was built shortly after the Norman conquest. Hamelin de Balun, one of William the Conqueror’s supporters, chose the site for its vantage point over the River Usk. At first, it was a simple motte-and-bailey fort made of timber.
In the 12th century, stone defences replaced the wooden ones. Control passed to the de Braose family, who were known for their harsh rule. In 1175, a notorious event took place here. William de Braose invited local Welsh leaders to a feast at the castle and had them killed. This became known as the Abergavenny Massacre.
The castle changed hands many times during the medieval period. It suffered damage during attacks by Welsh forces, including those led by Owain Glyndŵr in the early 15th century. Although it was repaired, its military role declined over time.
By the 17th century, the castle was no longer in use. During the English Civil War, Royalist forces slighted it, meaning they deliberately damaged it to prevent its reuse. In the 19th century, parts of the site were turned into a public park. A hunting lodge was built in the ruins and now houses the Abergavenny Museum.
Features and Layout
The castle was originally built as a motte-and-bailey design. This means it had a raised mound (the motte) with a wooden tower on top, and a lower enclosed area (the bailey) surrounded by a ditch and fence. Over time, stone replaced the timber.
The most prominent feature today is the ruined stone keep on the motte. It once held the lord’s private quarters and served as the last line of defence. Some curtain walls still stand, giving a sense of how the castle enclosed its inner grounds.
You can still see parts of the gatehouse foundations. These would have controlled access to the site. Arrow slits and traces of defensive towers remain in the walls. The structure was never especially large, but it was heavily fortified for its time.
In the 19th century, a small hunting lodge was built on the grounds. This later became the museum. Today, you can walk along the stone remains and explore the open green space where the bailey once stood.

Legends and Stories
The most well-known story tied to the castle is the 1175 massacre. William de Braose invited a group of Welsh leaders from the neighbouring kingdom of Brycheiniog to a Christmas feast. Once inside the castle walls, they were murdered. De Braose claimed it was revenge for the killing of his uncle, but the act was seen as a betrayal of hospitality. The event caused lasting resentment and distrust.
Locals sometimes refer to this event as “the Bloodiest Christmas,” and it remains one of the darkest episodes in the history of the Welsh Marches. Some say the castle is haunted by those who died in the massacre, though reports of paranormal activity are rare.
There are also tales of hidden tunnels under the grounds, possibly linking the castle to nearby buildings. These have never been confirmed by archaeology, but the rumour persists.
