GRIANAN AILEACH (GRIANAN AILLIGH), ring fort.

At the top of the hill behind the little hamlet of Burt in County Donegal sits a 2,000 plus year old ring fort, Grianan Aileach (this is the way it is spelled in Donegal, but is sometimes spelled Ailligh by others). The fort is approached by driving up the hill to the side of the beautiful church at the base of the hill. It was the seat of the High Kings O'Neill for around seven centuries from the 5th century. To the left of the ring fort there is a burial mound (tumulus) which can be seen in the sketch to the left here. The burial mound is thought to date from 3,000 BC.
