Dún Dúchathair 2.61

Dún Dúchathair or simply Dúchathair, meaning \"black stone ringfort\", is a large stone fort on Inishmore in County Galway, Ireland. Due to erosion, it now sits on a rocky promontory that stretches out into the sea. On its outer side there are large walls, reaching 6 metres high and 5 metres wide. On the inside are the ruins of various rooms, possibly \"beehive\" huts. There is also evidence of a cheval de frise protecting the entrance.
