The coastal promontory of Crathie Point, west of Sandsend, shows evidence of a raised bank and ditch, effectively creating a simple enclosure, defended from landward approach. Outside the ditch are faint remnants of a palliade trench. There are no apparent interior features to the fort, so it is hard to get a clear idea of when or how it was used.
If you follow the coast about a mile further to the west you will come to Findlater Castle, a ruinous medieval fortress set in a landscape that suggests an earlier fort, possibly associated with the fort at Crathie Point.
