Kinloch Castle is an Edwardian mansion located on Kinloch, on the island of Rùm, one of the Small Isles off the west coast of Scotland. It was built as a private residence for Sir George Bullough, a textile tycoon from Lancashire whose father bought Rùm as his summer residence and shooting estate. Construction began in 1897, and was completed in 1900. Built as a luxurious retreat, Kinloch Castle has since declined. The castle and island are now owned by NatureScot, who operated part of the castle as a hostel until 2015. The Kinloch Castle Friends Association was established in 1996 to secure the long-term future of the building.
