Eighteenth-century soldiers paved a military highway north from Ballater to Corgarff Castle, an isolated tower house on the moorland with a star-shape defensive wall that's a curious replica of Braemar Castle. Corgarff was built as a hunting lodge for the earls of Mar in the 16th century. After an eventful history that included the wife of a later laird being burned alive in a family dispute, the castle ended its career as a garrison for Hanoverian troops. The troops were
responsible for preventing illegal whisky distilling. Reconstructed barracks show what the castle must have been like when the redcoats arrived in 1746.
