Walwyn’s Castle

Walwyn’s Castle stands on a bend in a narrow valley about five kilometres north of the River Cleddau’s mouth in Pembrokeshire. It was built by Norman lords after 1093 on an earlier Iron Age ringwork, turning the site into a motte. The castle occupies a promontory fort with steep slopes on three sides and a high bank on the fourth. Its position gave the Normans good links to the sheltered harbour of Milford Haven. The site became the centre of a medieval barony with two dependent castles at Benton and Dale. Unlike many motte-and-bailey forts, Walwyn’s Castle shows no stonework today. Its earthworks are more elaborate than usual, providing strong defences for the small garrison. The lack of masonry suggests the lord preferred earth ramparts over walls. Visitors walk among grassy ramparts and the remains of the inner bank. The valley setting is quiet, with views along the wooded slopes. The site is hard to reach, adding to its sense of isolation. A low mound marks the motte, and the surrounding ditches are still deep. The place feels older than its medieval years, echoing the Iron Age ringwork beneath.
