Dún Aonghasa

Perilously perched on a sheer sea-cliff, Dún Aonghasa defiantly faces the Atlantic Ocean. It is the largest of the prehistoric stone forts of the Aran Islands.

The fort consists of three massive drystone defence walls. Outside them is a chevaux-de-frise – that is, a dense band of jagged, upright stones, thousands in number. A devastatingly effective way to impede intruders, the chevaux-de-frise surrounds the entire fort from cliff to cliff.

Dún Aonghasa is over 3,000 years old. Excavations have revealed significant evidence of prehistoric metalworking, as well as several houses and burials. The whole complex was refortified in AD 700–800.

The visit involves a short hike over rising ground and rough, natural rock, so come prepared with boots or strong walking shoes. Be careful, too, when walking near the cliff – there is no fence or barrier at the edge of the 87-metre drop.

Visitor safety information: The site is about 1km from the Visitor Centre and is approached over rising ground.
