Fair Head or Benmore (Irish: An Bhinn Mhór; The Great Cliff) is a five-kilometre-long (three-mile), 200-metre-high (650-foot), mountain cliff, close to the sea, at the north-eastern corner of County Antrim, Northern Ireland. The cliff's sheer and vertical 100-metre-high (350-foot) dolerite rock face is shaped into distinctive vertical columns like organ pipes, which formed 60 million years ago when a sill of igneous rock was injected between horizontal Carboniferous sediments.
