Skibo Castle (Andrew Carnegie estate)

The Scottish-American steel magnate purchased Skibo Castle as a summer residence in 1898 for £85,000. However its condition had declined so much by this time that a further £2 million was spent on improvements, including an increase in area from 16,000 sq.ft. to over 60,000 sq.ft., plus the creation of Loch Ospisdale and an 18-hole golf course.

Skibo stayed with the Carnegie family until 1982. It was later purchased by businessman Peter de Savary and used as the foundation of a private members club, the Carnegie Club.
