Bronllys Castle is a Norman motte-and-bailey fortress located near the town of Talgarth in Powys, mid Wales. Built in the early 12th century, it stands out for its round stone tower, which replaced the original timber keep.

Although only parts of the structure remain, Bronllys offers a clear look at early medieval castle design and the tensions along the Welsh Marches. The castle was once a stronghold of power for Marcher Lords trying to assert control over this contested borderland. Today, its ruins offer sweeping views of the surrounding countryside and a quiet space to explore Welsh history.

A Brief History

The castle began as a timber motte-and-bailey fortification built by Richard Fitz Pons around 1100. He was a Norman knight tasked with securing Norman control over the Welsh borderlands. The castle overlooked an important route through the Black Mountains.

In the mid-12th century, the original timber structure was replaced by a round stone keep. This upgrade made the castle more resistant to fire and siege. Around this time, the castle passed to Walter de Clifford, a powerful Marcher Lord with strong influence in the area.

In 1165, the keep was badly damaged when a fire broke out during a domestic dispute. The blaze caused the collapse of part of the tower, killing Walter de Clifford’s son. The tower was later repaired and remained in use for centuries.

Bronllys Castle was never the site of a major battle, but it changed hands several times as control of the Welsh Marches shifted. It was eventually absorbed into the Crown estates in the late medieval period. By the 16th century, the castle had fallen into disuse.

Today, only the stone keep and earthworks remain, offering a clear example of how Marcher castles evolved over time.

Features and Layout

The castle was originally built as a motte-and-bailey structure. The motte, or mound, still rises sharply above the surrounding ground. At its summit stands the remains of a 13th-century round stone tower. This was once a strong defensive keep, offering clear views across the River Llynfi and nearby routes through the Black Mountains.

The stone tower is the most complete part of the castle today. It is three storeys high, with narrow arrow slits and traces of a spiral staircase. The interior is now roofless, but you can still climb partway up and view the surrounding landscape.

Below the tower, earthworks show where the bailey, the enclosed courtyard, once stood. Timber buildings such as stables or a hall would have occupied this area, though no structures survive.

Defensive ditches surround the motte. These would have made it harder for attackers to reach the walls. The castle’s original timber gatehouse is lost, but the layout suggests a single entrance from the west.

The castle is small, but it shows key features typical of early Norman fortifications, including layered defence, a central stronghold, and commanding views of the landscape.

Legends and Stories

The castle is not widely known for ghost tales or popular legends, but one tragic event has passed into local lore. In 1165, a fire broke out in the tower during a domestic argument. The blaze caused a structural collapse that killed Walter de Clifford’s young son. The event left a mark on the Clifford family’s legacy, and some later stories hinted that the tower was cursed or unlucky.

Although there are no surviving myths or ghost stories tied directly to the site, its isolated setting and ruined tower often inspire local imagination. Visitors sometimes speak of a quiet, uneasy atmosphere, particularly at dusk.

Because of the castle’s association with the Marcher Lords, it also features in regional tales of shifting loyalties and border conflicts. These stories, while not tied to specific people or events at Bronllys, reflect the unstable nature of life along the Welsh Marches in the medieval period.
