Description

This building comprises a police station and magistrates court constructed in the 18th century. The building is built of squared and roughly coursed white stone with red sandstone dressings and green slate roofs. It has an asymmetrical design, with the police station to the left and the magistrates court set back to the right.

The police station is a two-storey, five-bay range with an advanced outer gable on the left, originally intended as domestic accommodation. The entrance to the police station is on the side, approached via a segmentally arched canopy porch supported by bold brackets, with a tall, three-tier mullioned and transomed stair window above. The police station has three-light mullioned and transomed windows on each floor, and a two-light attic window with a segmentally pedimented head. A string course runs over the ground floor and continues across the main range, which features a central gable. The gable has paired mullioned and transomed windows on the ground floor, and a recessed five-light bow window above. Further three-light mullioned and transomed windows are present on each floor of the left-hand bay. The main entrance is in the lower right-hand bay, featuring a shallow archway with a two-centred arched doorway and side light, with mullioned overlights filling the remainder of the archway. Lettering is present in the spandrels of the arch above, and a three-light mullioned and transomed window is situated on the first floor. A tower is advanced to the right, featuring a pedimented panel containing three-light mullioned windows on each floor, with a low relief coat of arms between them, and a relief in the pediment. Corbelled pilasters mark the angles below the upper stage, which is red sandstone, and has three splayed lancet windows and an embattled parapet.

The magistrates court is set back behind the tower, with an advanced entrance bay joining the tower. This entrance bay has doorways on either end in small moulded arches, and a central pediment with a coat of arms supported by strapwork pilasters, above a mullioned window. An advanced, flat-roofed ante-room is situated to the upper right, with lancet windows and ball finials at the angles of the parapet. The upper gable wall features a Dutch gable and a Palladian window with a lunette above. Three semicircular clerestory windows are present in the main range.

A low boundary wall, stepped with shallow copings and formerly carrying a cast iron railing, originally enclosed a narrow forecourt to the police station and court building. Cast iron gates and sandstone piers, with shallow pyramidal copings, complete the entrance.
