Dumbarton Castle is the oldest fortified stronghold in Scotland, if not Britain. It is known to have been inhabited in the Iron Age, and was an important outpost in Roman times guarding the western approaches to the Antonine Wall. Written records mentioning "Alt Clut" (Rock of Clyde) date back to the 5th Century, and it's seen a lot of action since then.
The Gaelic name "Dun Breatainn" means 'Fort of the Britons', a sign of the place's importance in the Dark Ages when the Kingdom of the Britons extended from the top end of Loch Lomond all the way down the west side of the country to north Wales and was ruled from here (did someone mention Arthur?). Merlin, in his Scottish wild-man form of Lailoken, is said to have visited here, and the list of illustrious guests throughout history includes Mary Queen of Scots, who sought refuge here as a child before sailing to France to marry the young Dauphin. William Wallace was also held captive here before being taken to London to meet his grisly execution. The Castle was still manned as a military base in World War 2.
But all this history is barely evident today, and a visit to the castle should be enjoyed mainly for the exercise in climbing the 547 steps to the highest point, and the stunning views of the Clyde, and Ben Lomond to the north. There isn't much else to see to be honest - the guardroom has a small exhibition on the castle's history, there is the magazine on the lower of the two summits, and the 'French prison' where captured Napoleonic soldiers were held - but this was closed for refurbishment on my visit. But other than that, it's a lot of steps and a good workout!
There is a very small gift shop but the selection of the usual tat was hardly inspiring. Go for the views and the exercise. read more
