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. This site, also known as Llandeilo Graban Motte, is situated near the end of a ridge running eastwards between two streams. It is c.34m in diameter at its base and stands up to c.7m above the base of the ditch, which is c.7m wide and c.2m deep. The summit is c.20m in diameter and is flat with no obvious structural features. (Scheduling Report)

Gatehouse Comments
