Carriganass Castle just east of Kealkil, near Bantry, stands guard over the crossing of the River Owvane where a bridge carries it across a rocky gorge. It was built around 1540 by Diarmuid 'An Phudair' O'Sullivan, the chieftain of the O'Sullivans Beare. It occupies an imposing position on an outcrop of rock overlooking the turbulent river. Probably the best surviving structure of the clan, it is being beautifully preserved to arrest further decay. Although one side of the tower house as fallen, parts of the bawn wall and corner defences remain, giving one a good impression of how it must have appeared in its heyday.
