Old Courthouse, Bolgam Street, Campbeltown

This building probably dates from the mid-18th century and incorporates earlier fabric. It comprises a symmetrical, 2-storey, 3-bay block fronting a small stone flagged central courtyard with additional ranges to the north, east and west. It was remodelled in 1852-3 for use as a court house and police offices with a jail. The principal elevation to Bolgam Street is rendered with raised margins at the openings and projecting window cills and a moulded eaves course. There is a central pend and the first floor windows are round-arched.

The east courtyard range is 3 bays. It has a stone forestair with a cast iron balustrade leading to pedimented doorpiece. This doorpiece has a stepped pyramid finial with a carved serpent. There is a 2-leaf timber door with an arched-pane fanlight. The west courtyard range is 3 bays with centre door and dormer windows breaking the eaves.

The windows on the Bolgam Street elevation are boarded up and in 2010 were described as predominantly 12-pane glazing in timber sash and case frames with 16-pane glazing pattern in the upper sashes of the round-arched windows. The ground floor windows have iron bars. The roof has grey slates and there are coped brick chimney stacks with those to the rear ranges being harled. The rainwater goods are cast iron..

The interior was seen in 2010. The first floor hall (former courtroom) has a fireplace with Tusan columns supporting a corniced shelf. There is an open timber roof structure with large timber corbels supporting A-frame trusses. The doors and windows have moulded architraves. Some simple moulded cornicing survives. The roof of south range has an early single rafter structure with ashlar posts, braced by sarking boards without further longitudinal supports.
