Kinross House is a late 17th-century country house overlooking Loch Leven, near Kinross in Perth and Kinross, Scotland. Construction of the house was begun in 1686, by the architect Sir William Bruce as his own home. It is regarded as one of his finest works, and was called by Daniel Defoe "the most beautiful and regular piece of Architecture in Scotland". The house, which is undoubtedly the most important early classical mansion in Scotland, retains most of its original internal decoration. It has been occupied for 200 years as the home of the Montgomery family, who purchased the property in the late 18th century.
