Inverlochy Castle has the slightly sad air of a structure overtaken by history not once, but twice. First it was made redundant as the military focus of the area by the building of a more modern citadel at the nearby head of Loch Linnhe by Cromwell in 1654. The large fort built on the site of this citadel in 1690 was named Fort William after the King, and the settlement that grew around it took the same name.
