Mount Stuart Castle

Mount Stuart House, on the east coast of the Isle of Bute, Scotland, is a country house built in the Gothic Revival style and the ancestral home of the Marquesses of Bute. It was designed by Sir Robert Rowand Anderson for the 3rd Marquess in the late 1870s, replacing an earlier house by Alexander McGill, which burnt down in 1877. The house is a Category A listed building.
