Dún Aonghasa is a dramatic stone fort standing defiantly on a cliff-top almost 300 feet above sea level.
Perched on a cliff overlooking the Atlantic Ocean, Dún Aonghasa is the largest of the prehistoric stone forts of the Aran Islands. The fort consists of three massive dry-stone walls and a chevaux-de-frise, a dense band of jagged, upright stones, surrounding the fort from cliff to cliff, designed to impede attackers. Originally constructed c.1100BC, it was re-fortified around 700-800 AD. Excavations revealed significant evidence of prehistoric metalworking, as well as several burials.
Services available include exhibitions about the fort, and guided tours of the fort.
