James Bullough bought Isle of Rum 1886 for £35,000. His Son George inherited much of the family fortune and spent £15 million (in today's money) constructing the castle. Building began in 1897 with 300 craftsmen, and was finished in 1900.
The red sandstone was from a quarry in Corrie, Arran.
For the gardens 250,000 tons of soil was imported, a walled garden and greenhouses built, water features, bridges and appropriate ornaments. The greenhouses were for peaches and grapes and other fruit associated with the Mediterranean. Sir George died in 1939 leaving the castle to his wife who in turn sold it to Scottish Natural Heritage for around £1 per acre.
Sadly the castle has fallen into disrepair but SNH are paying for the upkeep. The hostel in the back will have to move however. The building featured in BBC's 'restoration' in 2003.
