Description

The watch tower, located to the northwest of St. Justinian's, is an early 20th-century circular look-out tower made of colourwashed rubble stone. It features a slate octagonal roof and a modern red dragon iron weathercock. The tower has two storeys, with four upper windows situated under the eaves and similar windows on the ground floor facing south and west, all of which are modern 4-pane sashes. There is a door on the east side, and the lower openings have painted cambered brick heads and painted slate sills. The tower was gutted and is currently under reconstruction as of 1989.
