Dumbarton,Scotland

Dumbarton is a town on the River Clyde, west of Glasgow where you will find Dumbarton Castle. Founded in the fifth century, Dumbarton was once the capital of the ancient Kingdom of Strathclyde. The key to the town’s original success was the volcanic rock, which is now home to Dumbarton Castle. This dramatic volcanic plug, Dumbarton Rock, in-filled the crater of a volcano that was active 350 million years ago. The rock is well exposed and inaccessible on all sides.
