The remains of an RIC Barracks at Islandeady, County Mayo. The building dates from the first half of the 19th century when constructed on a plot provided for the purpose by local landlord Sir William Palmer who lived at Castle Lacken, today also a ruin. Of two storeys and three bays, the barracks is a handsome structure, with the focus on its cut-limestone doorcase. There is a small yard to the rear with holding cell. It remained in operation until early 1920 when, like many other remote buildings held by the force, it was abandoned owing to the War of Independence. In June of that year, the barracks was gutted by fire, again a common circumstance, and has remained a ruin ever since.
