Dunnottar Castle (Scottish Gaelic: Dùn Fhoithear, "fort on the shelving slope") is a ruined medieval fortress located upon a rocky headland on the north-east coast of Scotland, about 3 kilometres (1.9 mi) south of Stonehaven. The surviving buildings are largely of the 15th and 16th centuries, but the site is believed to have been fortified in the Early Middle Ages.
