Corgarff Castle, in a wild and lonely setting at the head of Strathdon, on the flank of the Cairngorms and guarding the quickest route from Deeside to Speyside. The castle was built in about 1550 and has an outer wall added in 1748. More pics and info: https://www.undiscoveredscotland.co.uk/strathdon/corgarffcastle/index.html #Scotland #Strathdon
