This illustration is a reconstruction and cutaway visualisation which I was commissioned to produce for Historic Scotland. It shows Kilchurn castle in Argyll as it may have looked at the end of the seventeenth century undergoing the final stages of its last major alteration - the addition of the north-west range and L-shaped barracks which are shown unfurnished. When completed, these barracks would have accommodated a company of some 200 men. This became the first purpose-built barracks in Scotland and was used as a Government garrison during the 1715 and '45 Jacobite risings. A large kitchen and several vaulted cellars occupied the ground floor underneath. In this illustration are pictured several masons applying a harling cover to the walls of the barracks in the inner courtyard while Sir John Campbell of Glenorchy (First Earl of Breadalbane) inspects the work.
