was constructed around 1440 by the Knox family who, in the 19th century, took the title of Earl of Ranfurly in the Peerage of Ireland. The building was three stories high and the remains of the Castle are located in the grounds of the Old Course Ranfurly Golf Club. In 1665 it was sold to the Cochrane Earls of Dundonald, later it was sold to the Hamiltons of Holmhead, then to the Aitkenheads.
Victorian settlement
The settlement of Ranfurly originated primarily in the 1880s to 1910s, with quality stone-built houses and some fine villas in the higher land above the village following the expansion of the area and the arrival of the railway in Bridge of Weir in 1864. Significant in the area was the Ranfurly Hotel which was built in 1882 in the Scots Baronial style, designed by architect Robert Raeburn for the Bonar family of Ranfurly estate and an extension designed by James Miller. It was closed as a hotel prior to the First World War and seen a number of uses since. In the 1990s, Gary Pearson began to restore Ranfurly Hotel to its original Victorian beauty. Speaking of the building, Pearson said "what had once been my dream castle looked more like a crumbling row of tenements. But it's such a spectacular building, it would have been criminal not to preserve it." Ranfurly Hotel, now Castle Terrace, has been renovated into private apartments and shops.
Governance
Ranfurly is part of Bridge of Weir for local government purposes, which is in turn part of the council area of Renfrewshire, as well the historic county of Renfrewshire which has wider boundaries and retains some official functions, for example as a registration county and lieutenancy area. For elections to Renfrewshire Council, Bridge of Weir is part of ward 10, named 'Bishopton, Bridge of Weir and Langbank', which elects three of Renfrewshire's forty three councillors. T Bridge of Weir is also one of Renfrewshire's twenty-seven community council areas, which represents the Ranfurly area. Historically, Bridge of Weir was split between the civil parishes of Houston and Kilellan and Kilbarchan, with Ranfurly falling into the latter.
Religion
The former Ranfurly Church merged with St Machar's Church, also in the area, to form the Ranfurly St MacharChurch in 1968 within the Church of Scotland. The latter church building, constructed in 1878 in the Gothic Revival style, is now used by the joint congregation. The former Ranfurly Church has been converted into private residences. St Machar's, and later St Machar's Ranfurly, has been the historical parish church of Bridge of Weir since the area's elevation to a quoad sacra parish in 1887.
