Dunguaire Castle is a 16th century tower house located in Kinvara on the shores of Galway Bay.  The castle was built in 1520 by the O’Hynes clan and passed into the hands of the Martyn’s of Galway in the early 17th century.  Richard Martyn, Mayor of Galway lived here until 1642 and the Martyn’s of Tulira Castle, owned the castle until this century.
