The precipitous knoll at the seaward end of Harrabrough Head, which is an inaccessible promontory jutting out from the foot of the coastal cliffs, is crowned by a substantial rectangular structure, and the approach from the NE across a narrow neck is also barred by a ruinous wall. The structure on the summit is probably a medieval building, measuring 21m from NW to SE by 6m transversely within a wall reduced to a bank 3.5m in thickness by 1.5m in height. The outer wall across the neck has been reduced to a stony scarp, but is broken by a gap at its S end, where a path approaches obliquely up the slope from the rocks on the shore below. The area cut off is riven with geos leading into sea arches and extends to no more than 0.7ha. The relationship between the building and the outer wall is unknown.

N/A
Assuming that the building is not later, this may be some form of medieval castle.In the absence of excavation, there are neither stratified artefacts nor radiocarbon dates to provide a chronology for the defences.
