"Dunlough Castle, also known as Three Castles, is an early 13th-century fortification located at the head of Dunlough Bay on the Mizen Peninsula in County Cork, Ireland. The remains of the three fortified towers, the middle of which was the main residential area, are all that is left of this once important stronghold. Surrounded by a moat carved out of the rock, Dunlough Castle is accessible only by a single narrow stone bridge, making it one of the more remote and dramatic castle ruins in Ireland." - Travel + Leisure Editors
