Dunnottar Castle, Scotland (by michael prince)
Dunnottar Castle (from Scottish Gaelic Dùn Fhoithear, “fort on the shelving slope”[1]) is a ruined medieval fortress located upon a rocky headland on the north-east coast of Scotland, about two miles (3 km) south of Stonehaven. The surviving buildings are largely of the 15th–16th centuries, but the site is believed to have been an early fortress of the Dark Ages. (wikipedia)
