Menlo Castle is built on the site of, and incorporates portions of, a mid-16th century tower house.
[2][3] Several sources date the original tower house to 1569,[4] and it was recorded as being occupied by a Thomas Colman in 1574.
[2] Later occupied by the Blake family,[4] the castle was extended to include a two-bay four-storey block during the 18th century.
[8][9] The castle was largely left to ruin following the fire, and the Blake estate was divided by the Land Commission in 1923.
[10] The castle site and its surrounds were acquired by Galway City Council under a compulsory purchase order (from five separate land owners) in July 2000.
