Carrickabraghy Castle is located on Doagh Island in co.Donegal. This was was one of a network of castles built to defend and protect the lands belonging to the O’Doherty clan in the late 1500’s. This was a perfect hideaway as Doagh Island is an island off an island on the Inishowen peninsula. It was occupied by Phelemy Brasleigh O’Doherty and was later chosen by Cahir O’Doherty to plan his famous revolt that led to the Flight of the Earls in 1607. Further back in time between 834 and 1200 this location, according to the Annals of the Four Masters, was the site where the McFaul Clan resided. The McFaul’s were a powerful sept of the ruling O’Neill Chieftains of Ulster. Recently ancient rock art from the Bronza Age was found near this location.
