A mutilated ditched mound, c.34m in diameter and 3.9m high, there being traces of the ditch only on the SE. There is no trace of a bailey or other outworks. (Coflein)

3.9m high motte with traces of ditch surviving on the SE. Partly in use as ornamental garden it has been deliberately mutilated on lower slopes of N and W sides. House extension gave opportunity to observe extent of motte ditch. Top of ditch recorded, 5m wide, below yard surface and modern layers (Jones, N.W., 1988a, 73). Considered by Spurgeon as originally also having a bailey (Manley, J, Grenter, S & Gale, F, 1991). (Clwyd Powys Archaeological Trust HER)

The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). A motte is a large conical or pyramidal mound of soil and/or stone, usually surrounded by either a wet or dry ditch, and surmounted by a tower constructed of timber or stone. Tomen Cefn Glaniwrch consists of a mutilated ditched mound, c.34m in diameter and 3.9m high, with traces of the ditch only on the south-east. A possible earlier rectangular enclosure, or associated bailey, has been suggested from LiDAR evidence. (Scheduling Report)
