The Gatehouse website record for Tump Terret, Trellech

Also known as, or recorded in historical documents as; Trelleck; Trillech; Twyn Tirret

In the community of Trellech United. In the historic county of Monmouthshire (Modern authority of Monmouthshire, preserved county of Gwent).

Large, earthen steep-sided circular mound, c.36m in diameter and 5.5m high, with remains of counterscarp to the S. The ditch that originally encircled it survives only on the north side. All traces of the bailey have gone, however, the presence of Court Farm to S, may indicate a further enclosure in this area. Geophysical survey in area of motte indicates the presence of structural remains in area of bailey enclosure to N and NE. Structural features on motte-top are thought to relate to a C19 summer house. The history of the castle is obscure; but it is known to have been in existence before 1231. Trellech was within the Norman lordship of Usk, and the castle presumably had some manorial administrative function.
The motte and bailey at Trelech can be identified, on the basis of size and shape, as one of the early type of castles built during the initial conquest of the area. The steepness of the motte and the surrounding ditch also show that inner defence was also a major issue. The site is located on the edge of a ridge of land with the motte at the steepest side and the bailey separated from it by a ditch. The bailey stretches to the north and may be of considerable size judging by the modifications to the natural terrain that are evident throughout the village. (Phillips)
