Caherdooneerish also known as Caherdoonfergus stands high above Black Head not far from the harbour village of Ballyvaughan, County Clare, Ireland (Irish: Baile Uí Bheacháin, Contae an Chláir, Éire). This fort is about twenty metres in diameter with stone walls standing at four metres in places. Not least in making the effort to climb up to this fort is the commanding view presented over Galway Bay (Irish: Loch Lurgain or Cuan na Gaillimhe). There is an interesting passage written on Black Head, Caherdooneerish, in the book Archaeology of the Burren: Prehistoric Forts and Dolmens in North Clare by Thomas Johnson Westropp. Thomas Johnson Westropp (16 August 1860 – 9 April 1922) was an Irish antiquarian, folklorist and archaeologist. He drew many detailed sketches of buildings, grave slabs and other archaeological remains throughout Ireland. There is a link to his passage on Caherdooneerish via Clare County Library below.
