Measuring roughly 7.3 metres east to west and 5.5 metres north to south, the rectangular ruin is modest in scale, but its origins give it an unusual character: the mill is said to have been built using stone robbed from a nearby tower house, a type of fortified residence common across late medieval Ireland, typically a tall, narrow structure with thick defensive walls.

The connection between the two structures is more than architectural curiosity. Reusing stone from a castle to raise a working mill suggests a particular moment of transition, when a fortified building had either fallen into abandonment or been deliberately dismantled, and its dressed stone was too useful to leave lying in the ground. The tower house in question is recorded alongside the mill, located just to its east, and the two sites together point to a landscape that moved, at some point, from defensive occupation to agricultural industry. The exact date of that shift is not recorded, but the physical evidence of the mill's fabric quietly preserves it.
