These buildings were rarely grand. The RIC operated from a network of small, often austere outposts, many of them converted farmhouses or purpose-built two-storey structures with thick walls and barred windows, designed as much for security as for administration. That a barracks existed here at all speaks to how thoroughly the colonial police presence was distributed across even thinly populated parts of Connacht.

Beyond its classification as a recorded monument, the specific history of this particular barracks, its construction date, the years it was active, and what became of it after the force was disbanded in 1922, remains to be fully documented in the public domain. What is known in general terms is that many such rural outposts were burned or abandoned during the War of Independence, when attacks on RIC barracks became a deliberate strategy to disrupt British administration. Others simply fell into disuse, absorbed into farm holdings or left to decay. The townland name Knockdrummore, derived from the Irish meaning something close to the big ridge of the drum or rounded hill, suggests the kind of elevated, sparsely settled ground where a small police presence would once have kept watch over a wide area.
