Tump Terret is a ditched mound, c.36m in diameter and 5.5m high, with the remains of counterscarp to the south. The Castle is mentioned in 1231, and referred to as 'site of' in 1306.
A geophysical survey in the area of the motte indicated the presence of structural remains in the area of the bailey enclosure to the north and north-east. Structural features on the motte-top are thought to relate to a nineteenth-centuryth century summer house (Soulsby 1982 (Monmouth Antiquary 4.3-4), 41).
The presence of Court Farm to the south (Nprn43389), may indicate a further enclosure in this area.
