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. The Tudor Gothic architecture is the work of Robert Lugar. In 1915 Balloch was bought by Glasgow City Corporation, and has been leased by West Dunbartonshire Council since 1975. The estate was designated as a country park in 1980, and since 2002 has been part of Loch Lomond and The Trossachs National Park. Although the house has been periodically used for visitor facilities and council offices, it is now included on the Buildings at Risk Register. Balloch Castle is a category A listed building, and the estate is included on the Inventory of Gardens and Designed Landscapes in Scotland.
Loch Lomond (/ˈlɒx ˈloʊmənd/; Scottish Gaelic: Loch Laomainn – ‘Lake of the Elms’) is a freshwater Scottish loch which crosses the Highland Boundary Fault, often considered the boundary between the lowlands of Central Scotland and the Highlands. Traditionally forming part of the boundary between the counties of Stirlingshire and Dunbartonshire, Loch Lomond is split between the council areas of Stirling, Argyll and Bute and West Dunbartonshire. Its southern shores are about 23 kilometres (14 mi) northwest of the centre of Glasgow, Scotland’s largest city. The Loch forms part of the Loch Lomond and The Trossachs National Park which was established in 2002.
