Aughnanure Castle was built in the 16th century as a stronghold of the O'Flaherty clan, and is renowned for its unusual double bawn. It lies in picturesque surroundings close to the shores of Lough Corrib.

In 1546, the O'Flaherty's motto "Fortune favours the strong" and the powerful Mayo O'Malley's Motto "Powerful by land and by sea", were joined in the marriage of Donal an Chugaidh O'Flaherty and Grainuaile, or Grace O'Malley.

Standing on what is virtually a rocky island, the Castle is a particularly well-preserved example of an Irish tower house. In addition, visitors will find the remains of a banqueting hall, a watch tower, bastions and a dry harbour.
