Fiddaun Castle

Fiddaun is a mid-16th century Irish tower house in the Kiltartan barony of the Uí Fiachrach Aidhne, one of four O'Shaughnessy castles.

Fiddaun was most likely built by Sir Roger Gilla Dubh Ó Seachnasaigh, as he is the first mentioned living there and it is not known before his time.^[3]

This tower house is most noted for its well preserved inner bawn wall. It is located on private land and maintained by the Office of Public Works.^{[citation needed]}
