Standing on an outcrop of rock surrounded by forest and pasture, this sturdy fortress is a well-preserved Irish tower castle with an unusual double bawn (a fortified enclosure) and a still-complete watchtower that you can climb. It was built around A.D. 1500 as a stronghold of the “Ferocious” O’Flaherty clan, who dominated the region and terrified their neighbors in their day. The castle’s fireplaces are so big that you could fit a double bed in them. Aside from the tower the site is mostly a ruin, although you can wander through what remains of the banqueting hall. The grounds also contain the remnants of a dry harbor.
