Standing on a peninsula that cuts the Moray Estuary into a spur, this artillery fortress was built from 1748-1769 to position and protect George II's troops. These impressive fortifications had a sophisticated defence system; the bastions were called after the names of close relations. You can enter several of the buildings and realise what conditions were like in an 18C fort. Beyond the great armoured door and entrance tunnel is the guardroom, intended for officers and troops. The barracks show the development of daily life for a soldier from 1780-1868; even the officer's room is sparsely furnished. The great powder room could contain 2,500 barrels. There is also a very simple chapel.
