Mount Stuart House is a country house built in the Gothic Revival style situated on the east coast of the Isle of Bute, Scotland. It is the ancestral home of the Marquesses of Bute. The original house was constructed by Alexander McGill in 1719, but was redesigned by Sir Robert Rowand Anderson and rebuilt for the 3rd Marquess following a fire on 3 December 1877. It is built from reddish-brown stone; major features include the colonnaded Marble Hall at the centre of the main block, and the Marble Chapel with its elaborate spired tower. It was the first home in Scotland to be lit by electricity and claims to have been the first to have an indoor heated pool.Photograph credit: Colin
