The inquisition of 1541 mentions the castle as being a substantial structure with associated outbuildings including a threshing house and hemp yard while the Civil Survey of 1655 describes this site as an old castle with a thatched hall adjoining owned by the parsonage of Portrane. A later brick chimney can also be seen at the top of the tower. Samuel Lewis describes the castle as long since deserted in his Topographical Dictionary of Ireland in 1837 and notes the last occupant was Lady Acheson.
