Killeen Castle (Irish: Caisleán a' Chillín)[1] is a 15th-century tower house in Killeen townland, near Castlegar, County Galway, on the western coast of Ireland.
Originally built in 1493,[citation needed] the tower house and surrounding estate is historically associated with Blake family,[2] one of the 14 tribes of Galway. A farmhouse was constructed abutting the western wall of the tower house during the 19th century,[3] A large house was constructed on a hill to the north of the tower house, and with a gatehouse built on the N17 road. This large house (Killeen House) was burned down in 1922,[citation needed] together with many similar country houses of landed families, and subsequently demolished.[2] The land and castle was later purchased by a farmer from Tuam who had been managing the estate.[citation needed] The castle was sold and passed through several owners in the late 20th century,[4] being extended and converted into a private residence.[5][6]
