Dun Briste- Co Mayo

Dun Briste, an impressive sea-stack, estimated to be approximately 50 metres in height, stands 80 metres off Downpatrick Head, in the town-land of Knockaun, east of Ballycastle, Co. Mayo. The cliffs in the area, including the stack, were formed in the Lower Carboniferous period, a geological term applied to a time c. 350 million years ago, when the sea temperatures around Ireland were much higher than today.

According to the annals Dún Briste was separated from the mainland in 1393.

Some years ago, a helicopter landed several people on the stack; they were the first humans to set foot there for centuries. The party included Dr. Seamus Caulfield and his late father Padraig Caulfield, NT.; Fr. Declan Caulfield, R.I.P.; Noel Dunne, archaeologist; and Prof. Martin Downes, formerly of Castlebar. They camped there overnight and surveyed the surface where they found the remains of a medieval house, cultivation ridges, walls, and a broken quern stone (a stone used for grinding corn).
