Overgrass Tower and Adjacent Ruins

Overgrass Tower and the adjacent ruins are the remains of a tower house dating from the late 14th century or 15th century, along with a smaller building likely from the 18th century. The tower is constructed of massive squared stone and has a rectangular plan measuring 7.15 by 4.7 metres internally, with walls that are 1.8 metres thick. There is a slight projection for a staircase next to the entrance at the east end of the south wall. The walls of the tower stand to about the first-floor level, except for the south-east corner, and the side walls retain most of their facing and a chamfered set back two metres up. The south wall features the west jambs of both inner and outer doorways, while the east wall has a central loop and the west wall contains a central loop along with a garderobe shaft. Inside, there is a nearly complete slightly-pointed tunnel vault, which includes mural cupboards on the south side (now bricked up) and the east side.

Adjoining the west part of the north wall is the smaller rectangular building, which has walls that mostly stand to three metres high but lack architectural features aside from a small loop and a segment-headed oven recess, which was formerly at the rear of a hearth with a fire hood, located on the north side.
