Twmpath Garmon is a somewhat irregular mound, c.14-16m in diameter and 3.0m high, at the north angle of Castle Caereinion churchyard. It is identified as the motte of a castle recorded in 1156-1167. A series of yew tree-topped mounds in the south part of the churchyard may represent the bailey bank, indicating an enclosed area of c.70m by 60m.

It is alternatively a preaching mound, associated with the cult of Garmon (see Nprn's306787 & 306788).
