@ponderingadventurer: Dumbarton Rock consists of twin volcanic peaks that stand 240 feet above the rivers Clyde and Leven. The rock has been used as a fortification since before the Romans left Britain and stayed in use until WWII. It’s seen Roman trade, Viking raids, the alleged imprisonment of William Wallace, the sheltering of Mary Queen of Scots and German bombs during the 2nd World War. #Scotland #castles #History
