Castle Carra is a hall house and National Monument located in County Mayo, Ireland.
It lies on the edge of Black Hole, the deepest part of the lake.
[5] The plinth, bawn, outbuilding and gateways were added by the MacEvilly (Mac an Mhilidh).
[citation needed] The castle was surrendered to the Crown in the 1570s and granted to Captain William Bowen, who strengthened the bawn with a circular flanker with gunloops facing inland.
[6] It passed to Sir Henry Lynch, 3rd Baronet in the 1660s, and his descendants held it until the 19th century.
