Auldhame is a 16th century stone L-plan tower house, probably founded by Sir Adam Otterburn of Reidhall. Built on lands that originally belonged to the church, the only history of this laird's house is that was later held by the Colt family and by the 1700s it had been abandoned. Commanding the edge of a steep slope down to Seacliff beach, the house may incorporate material from an earlier building. The ruined main rectangular block is of three storeys with crow-stepped gables, a corbelled-out round bartizan and a vaulted basement. On the south-east angle is a square wing and projecting from the east wall is a rectangular tower, both have circular stair-turrets corbelled-out in their re-entrant angles. To the west, are the remains of outbuildings, a walled courtyard which contains a rectangular gate or doorway with moulded jambs and a defensive bank and ditch. Nearby is Tanallon Castle and 2 miles south is Whitekirk.
