Summary

Greenan Castle, a late 16th or early 17th century tower-house standing at the seaward end of this promontory, occupies the site of an earlier earthwork castle, which in its turn was built within the defences of an earlier fort, the latter known only from cropmarks. The remains of the earthwork castle are still visible, comprising a massive ditch 23m broad and 2m deep cutting off an area measuring 28m by 16m at the tip of the promontory, flanked on its landward side by a bailey measuring 70m from E to W by 26m transversely within a ditch some 13.7m in breadth by 3m in depth. The latter ditch is set immediately to the rear of the fort defences, which themselves comprise four ditches and at least two palisade trenches drawn in a shallow arc across the neck of the promontory. The W end of the innermost ditch of the fort is clipped by the bailey, but the scars of the second ditch and the outermost can still be detected at the cliff-edge on the NE, where the former is some 4.4m in breadth and the latter 3.7m. The interior, which is entirely occupied by the medieval castle, measures about 100m from NW to SE by a maximum of 75m transversely (0.59ha). An entrance causeway penetrates all four ditches close to the NE margin of the promontory, and at its outer end appears to be protected by a small hornwork springing from the W terminal of the outermost ditch.
