The Old Prison, including forecourt walls and gatepiers

The Old Prison is a former prison building consisting of three sections. It features two two-storey sections on the left and in the center, with the central bay being slightly advanced and topped with a pediment. There is also a single-storey section on the right. The building is constructed from squared limestone blocks, with the quoins and the central bay having a rock-faced finish. The roofs are slate with tiled ridges, and all sections except the right-hand bay have parapets. A stone lateral chimney with moulded cornicing and plain banding is located on the central bay.

The central bay has an entrance on the left with a recessed, part-glazed 20th-century door. To the right of this entrance is a window featuring a plain late Victorian sash, along with a small rectangular niche between the two openings. The first floor has two additional sash windows. Throughout the building, there are rusticated lintels and projecting stone sills, as well as a plain projecting string course between the floors that returns onto the recessed left-hand bay. The pediment is plain, with a projecting cornice band and parapet that also returns as described. The left bay contains plain sashes with flat lintels and sills, while the right-hand bay has two similar windows.

The interior was not inspected during the survey.
