Auldhame Castle is a ruined L-plan tower house standing on a ridge above Seacliff beach, about 3 miles east of North Berwick in East Lothian, and less than half a mile from Tantallon Castle.
The castle was built in the 16th century, probably by Adam Otterburn of Reidhall, Lord Provost of Edinburgh.
Part of a vaulted basement kitchen remains, with a bread oven.
Some plaster remains on the walls, including traces of a moulded decorative frieze.
A cemetery site in an adjoining field was excavated in 2008, the remains of at least 326 individual skeletons were noted, plus the foundations of a probable chapel with an estimated 9th century date (based on comparisons with similar structures).
