Tretower Court and Castle | Visit Welsh Castles
Tretower Court and Castle sit in the Usk Valley at the edge of the Black Mountains in Powys. The site includes a ruined Norman castle and a well-preserved medieval manor house. Together, they show how architecture in Wales changed from military stronghold to domestic residence.
The castle began as a motte-and-bailey in the early 1100s. Over time, stone fortifications replaced the timber structure. By the 14th century, the nearby court house had become the main residence. Wealthy gentry lived here, using the site to show their status and manage their estates.
Today, Tretower offers a rare chance to explore both a medieval fortress and a high-status house on the same site. The buildings are managed by Cadw and are open to the public.

A Brief History
The first castle at Tretower was likely built in the late 11th or early 12th century by Picard, a Norman follower of Bernard de Neufmarché. It began as a timber motte-and-bailey structure. By the mid-12th century, it was rebuilt in stone with a circular shell keep. A tall round tower was added around 1230 to improve defences and living space.
By the early 14th century, the castle had become less important. The owners, the Vaughan family, shifted their focus to building a more comfortable residence nearby. This became Tretower Court.
Tretower Court was expanded in stages through the 14th and 15th centuries. It was designed to reflect the growing power of the Vaughans, who were wealthy landowners and patrons of the arts. Sir Roger Vaughan, a key figure in the Wars of the Roses, lived here and fought at the Battle of Agincourt in 1415.
By the 1700s, the court had fallen into decline. It was used as a farmhouse until the 20th century. The castle, already in ruins, remained a local landmark.
Both the court and castle were placed under state care in the 20th century. They are now managed by Cadw and open to the public.
Features and Layout
Tretower Court and Castle share the same grounds but have distinct layouts. The castle, now a ruin, stands slightly uphill from the later court. It includes a circular stone shell keep, a large round tower, and parts of the curtain wall.
The shell keep is the oldest surviving feature, built on a raised motte. It once held timber buildings inside. The tall round tower, added in the 13th century, offered stronger defence and private chambers. Its walls are thick, and you can still trace the remains of arrow slits and fireplaces.
Tretower Court lies just south of the castle. It’s a fine example of a late medieval manor. The building has a timber-framed hall, a great chamber, and a range of service rooms. A courtyard lies at the centre, enclosed on all sides.
Much of the court has been restored to show how it may have looked around 1470. Painted walls, wooden furniture, and reconstructed hearths help bring the rooms to life. You can walk through the great hall, parlour, and buttery. A first-floor solar gives views of the courtyard below.
Outside, you’ll find herb gardens and a small orchard laid out using evidence from medieval records. These outdoor spaces reflect the site's shift from fortress to residence.

Legends and Stories
Tretower does not have the same wealth of ghost tales as some other Welsh castles, but a few stories still linger.
One local legend tells of a ghostly white lady seen near the old tower. She is said to walk the grounds at dusk, sometimes looking towards the hills. Some believe she may be linked to a noblewoman who lived here in the medieval period, possibly waiting for a husband who never returned from war.
Another story connects the site to Sir Roger Vaughan. He fought at Agincourt in 1415 alongside his father-in-law, Dafydd Gam, and was killed in battle. Visitors sometimes report the faint sound of horses or distant voices near the ruins, especially after dark.
While the court itself feels more domestic, the castle ruins carry an older, heavier atmosphere. These stories add to the sense of time layered across the site, even if they remain part of local folklore.
