Balloch Castle is an early 19th-century country house situated at the southern tip of Loch Lomond, in West Dunbartonshire, Scotland. Balloch was a property of the Lennox family from the 11th century, and the old castle was built in the 13th century. In the 19th century the estate was purchased by John Buchanan of Ardoch, who demolished the ruins of the old castle and erected the present building. Quoted from Wikipedia.
