Castle Toward (Scottish Gaelic: Caisteal an Toll Àird) is a nineteenth-century country house on the southern tip of the Cowal peninsula in Argyll, Scotland. Built in 1820 it replaced a late medieval castle, which was home of the Clan Lamont. In the Second World War it served as HMS Brontosaurus, and after the war it was sold to Glasgow Corporation. It was used as an outdoor education facility until closure in 2009. The castle is currently on sale for £1.75M.
