"Built in the 16th century by the O’Flaherty clan, this castle is located near the shores of Lough Corrib in County Galway. The well-preserved example of an Irish tower house was restored during the 1960s, and visitors can see the remains of a watch tower, banquet hall, bastions, and an underground stream. Three species of bats inhabit the castle, and supernatural events, including the appearance of the gamekeeper’s ghost and the wail of a banshee, have been reported. The castle is open for tours." - Travel + Leisure Editors
