Description

The Old Parish Church is a ruin dating to 1733, representing fragmentary remains of a former parish church situated within the grounds of the present church in Arrochar. The structure is built of rubble with harl pointing, featuring ashlar margins and dressings. The window and door surrounds are chamfered, and the building originally had a rectangular plan, though now only fragments of the south and west walls remain. Round-headed windows are a prominent feature, along with quoin strips.

The surviving south wall consists of a section rising to the arch head of a round-headed, slightly battered doorway, topped with a scrolled console keystone. The west wall was originally symmetrical, with round-headed windows flanking a tripartite entrance – the door is now blocked. Above the entrance is an elliptical datestone bearing the year 1733, and flanking oculi are also visible.

The current parish church is listed separately. References relating to the site can be found in G Hay’s Architecture of Scottish Post-Reformation Churches (page 254), and in North Clyde Estuary by F A Walker and F Sinclair (pages 117-118). A photostat copy of a plan dating to circa 1774 is held in the Scottish Record Office (RHP 9158).
