Description
Min y Twr features a circular two-storey tower constructed from local rubble masonry. The entrance is through a boarded studded door set in a round-headed doorway on the east side. The ground and first floors have pointed windows facing southeast and southwest, with all openings featuring plain hood bands. The tower has a castellated parapet that is somewhat offset above coved pseudo machicolations. To the west of the tower are earlier buttressed walls made of rubble, which form three sides of a rectangle; these walls were previously converted into a fives court and are now used as a garage.
Inside the tower, the walls are rendered and the floor is tiled. A spiral staircase with plain iron railings and balusters leads to the upper level. Beneath the staircase, there is a brick fireplace with a pointed relieving arch above a small hearth.
