This castle overlooking the harbour has been destroyed and rebuilt multiple times. The name means "fort of the jewels", presumably because it collected taxes from visiting vessels. The present building is a tower house from 1620: it fell derelict in the 20th century then was restored as a private residence. It's partly open for visits, and the Great Hall has an exhibition on local piracy, but you mainly come for the views from the battlements.
Dunasead Castle, sometimes known as Baltimore Castle, is a 17th-century fortified house situated in the town of Baltimore in County Cork, Ireland. The tower house is built on the site of an earlier Norman-era structure, which itself replaced an earlier Bronze Age ringfort. Traditionally associated with the chiefs of clan O'Driscoll, the castle was purchased and restored by members of the McCarthy family in the late 1990s, and partially opened to the public from 2005.
