Landmarks Civic buildings As the administrative centre of the county of Renfrewshire, Renfrew District and, currently, Renfrewshire council area, Paisley is home to many significant civic buildings. Paisley Town Hall, adjacent to the Abbey, was funded by the will of George Aitken Clark, one of the Clark family, owners of the Anchor Mills. In competition, Sir Peter Coats funded the construction of the modern Paisley Museum and Central Library (1871), also in a neo-Classical style. The Clarks and Coats families dominated Paisley industry until their companies merged in 1896. Renfrewshire's former County Buildings, Police Station and Jail on County Square were demolished in 1821, and the County Council then met in a newer neo-classical building, completed in 1890, which now houses Paisley Sheriff Court. Renfrewshire House, the modern headquarters of Renfrewshire Council, was constructed as Paisley Civic Centre. Designed by Hutchison, Locke and Monk following a competition, the building was designed to house offices of both the county and town councils. It was intended to become a civic hub for Paisley but the absence of any shops and non-council premises prevented this from happening. It became the home of the Renfrew sub-region of Strathclyde Regional Council in 1975 and of Renfrewshire Council in 1996. It is listed by the conservation organisation DoCoMoMo as one of the sixty key Scottish monuments of the post-war period. Other civic buildings of interest include the Russell Institute, an art deco building constructed in 1926.
