The castle as it stands today was completed in 1824. However, the original tower-house was erected on the site back in 1346 and, remarkably, only four families lived on the estate from that date until 2012 when the current owners, Ganten Scotland, bought the property. Blairquhan was also used as a replacement for Balmoral Castle in the 2006 Oscar-winning motion picture ‘The Queen’, starring Helen Mirren, as well as featuring in many other films and television programmes.
