Dumbarton Rock & Castle
Dumbarton Castle has the longest recorded history of any stronghold in Great Britain. It overlooks the Scottish town of Dumbarton, and sits on a plug of volcanic basalt known as Dumbarton Rock which is 240 feet (73 m) high. Throughout Dumbarton Castle’s long history it has been a royal residence and a fortress, and has many fascinating connections from the Vikings to the Scottish Wars of Independence. Mary Queen of Scots sailed to France from here as a child in 1548.
Dumbarton Castle was the centre of the ancient Kingdom of Strathclyde, supposedly visited by Merlin. It was later sacked by Vikings. It became a cornerstone of medieval royal power and latterly served as a military base and prison. You can explore its many fortifications with our interactive family trail.
