context_page_description: Dumbarton Castle has the longest recorded history of any stronghold in Scotland. It overlooks the Scottish town of Dumbarton, and sits on a plug of volcanic basalt known as Dumbarton Rock which is 240 feet high.
context_section_description: In medieval Scotland, Dumbarton (Dùn Breatainn, which means "the fortress of the Britons") was an important royal castle. It sheltered David II and his young wife, Joan of The Tower after the Scottish defeat at Halidon Hill in 1333.
  In 1425 the castle was attacked by James the Fat, youngest son of Murdoch Stewart, Duke of Albany, who had been imprisoned by King James I of Scotland on charges of treason. James the Fat became a rallying point for enemies of the King, and raised a rebellion against the crown. He marched on the town of Dumbarton and burned it, but was unable to take the castle, whose defender John Colquhoun successfully held out against James' men.
