The Kingdom of Strathclyde is home to a medieval capital with a castle that sits on volcanic basalt that was how high?
Kingdom of Strathclyde Strathclyde (lit. "Strath of the River Clyde"), originally Cumbric: Ystrad Clud or Alclud (and Strath-Clota in Anglo-Saxon), was one of the early medieval kingdoms of the Britons in "Hen Ogledd" ("the Old North"), the Brythonic-speaking parts of what is now southern Scotland and northern England. The kingdom developed during the post-Roman period. It is also known as Alt Clut, a Brittonic term for Dumbarton Castle, the medieval capital of the region. It may have had its origins with the Brythonic Damnonii people of Ptolemy's "Geography".
Dingwall Dingwall (Scots: "Dingwal" , Scottish Gaelic: "Inbhir Pheofharain" ) (] ) is a town and a royal burgh in the Highland council area of Scotland. It has a population of 5,491. It was formerly an east-coast harbour but now lies inland. Dingwall Castle was once the biggest castle north of Stirling. On the town's present-day outskirts lies Tulloch Castle, parts of which may date back to the 12th-century building. In 1411 the Battle of Dingwall is said to have taken place between the Clan Mackay and the Clan Donald.
