Downpatrick Head, Ballycastle, County Mayo, Ireland
Cut clean off from the mainland and lying 80 meters from the shore is a dramatic sea stack known as Dun Briste or “the broken fort”.
The sea stack got separated from the mainland in 1393 as a result of high seas, and the people living on the cliffs had to be rescued using ships ropes.
The sea stack is beautiful to behold because it has taken 350 million years for these layers upon layers of multi-coloured rock strata to build upon each other to create this amazing formation. Dun Briste is roughly 63 meter by 23 meters, and 45 meters high
