Tantallon Castle

Tantallon Castle is a semi-ruined mid-14th-century fortress, located 5 kilometres (3.1 mi) east of North Berwick, in East Lothian, Scotland. It sits atop a promontory opposite the Bass Rock, looking out onto the Firth of Forth. The last medieval curtain wall castle to be constructed in Scotland,[1] Tantallon comprises a single wall blocking off the headland, with the other three sides naturally protected by sea cliffs.
