Boyle Tower and garden entrance, Home of Compassion

The Boyle Tower and garden entrance, located at the Home of Compassion, date from the late 18th century and the tower is likely from the early 19th century.

The tower is built of stock brick in Flemish bond, topped with 20th-century pantiles on the gables. The garden entrance and a section of the wall are primarily made of red brick. The tower is three storeys high and square in shape, with one room on each level accessed by a ladder, and it has an adjoining garden entrance to the north.

The exterior features a two-storey tower with gable ends that have kneelers on the north and south sides, and an oculus on the north side facing the river. This side also includes a low external chimneystack. The east elevation, which serves as the entrance, has a brick stringcourse and a flat-arched entrance. The garden entrance features a west-facing wooden architrave beneath an elliptical arch, with a plank door. This entrance is set in a section of brick wall that adjoins the tower to the north. It leads into a round-headed brick tunnel with a gabled roof, which ends in a round-headed arch supported by brick corbels at the eastern end.

Inside the tower, there are remnants of a brick fireplace and wooden shelving on the ground floor, with ladder access to the upper levels.
