A castle mound or motte set astride the south-western defences of Caerau Roman fort (NPRN 92153). The mound is 23m in diameter and 4.5m high and its level summit is 5.0-9.0m wide. An erstwhile duckpond on the north-east may have been a vestige of a moat. Such mottes are often found in isolation and would have reared up beside otherwise unfortified courts or manor houses. (Coflein–ref. John Wiles 25.04.07)

Gatehouse Comments

Not quite sure what the Coflein report means by 'such mottes are often found in isolation' although this seems to be a reference to the lack of a bailey. Certainly there do seem to be a number of isolated mottes in Wales and the marches with associated farmhouses where the function of the motte is normally suggested as a watch tower (regardless of the view actually obtainable) but which may well have symbolised the knightly status of the farms tenant.
