The Guard House

The Guard House is a house that was formerly a guard room, dating from the early 17th century, with a later heightening likely from the 18th century. It is constructed of roughly coursed granite rubble, with the first floor made of coursed and roughly dressed granite. The building features a gabled slate roof with a truncated stack at the left end. It has a two-unit plan and stands two storeys high, with a two-window range.

On the ground floor, there are two late 19th-century four-pane casements set in chamfered surrounds, while the first floor has two 2-light six-pane casements. A 20th-century door is set in a chamfered surround made of three granite monoliths. The left gable end includes a 20th-century window in a chamfered rectangular surround, with remnants of removed mullions.

Inside, the building has ring beams supported by stone corbels and an open fireplace on the left, which is set in a chamfered surround made of three granite monoliths. The Guard House is depicted as a guard house in a plan of Hugh Fort by Colonel Christian Lilley, dated 1713.
