Duntrune Castle on Loch Crinan in Argyll, Scotland was sold to clan Malcolm in 1792. long before this.
In 1833, Campbell built "Duntroon House" out of stone with wide verandahs. In 1862 Robert's son George added a large two-storey extension. In its final form the house contained twenty rooms and is a great example of colonial architecture. It now serves as the officers' mess for the Royal Military College, Duntroon and is situated in the suburb of Duntroon, Canberra.
