This Iron/Dark age Fort is situated on the summit of Core Hill, immediately S of Kirkmaiden churchyard. It measures 28.3m by 21m within the inner rampart, which varies from a low bank 3.4m thick and 0.5m high, to a scarp up to 2.3m high externally. In the 19th Century when the interior was levelled for a bowling green, a stone axe was discovered.
