2 Best Sights in Aberdeen and the Northeast, Scotland

If you return east from Corgarff Castle to the A939/A944 junction and make a left onto the A944, the signs indicate that you're on the Castle Trail. The A944 meanders along the River Don to the village of Strathdon, where a great mound by the roadside turns out to be a motte, or the base of a wooden castle, built in the late 12th century. Although it takes considerable imagination to become enthusiastic about a grass-covered heap, surviving mottes have contributed greatly to the understanding of the history of Scottish castles. The A944 then joins the A97, and a few minutes later a sign points to Glenbuchat Castle, a plain Z-plan tower house.

Eighteenth-century soldiers paved a military highway north from Ballater to Corgarff Castle, an isolated tower house on the moorland with a star-shaped 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.
