Carlisle Castle is situated in Carlisle, Cumbria, England, near the ruins of Hadrian’s Wall. The castle is over 900 years old and has been the scene of many historical episodes in British history. Given the proximity of Carlisle to the border between England and Scotland, it has been the centre of many wars and invasions. Today the castle is managed by English Heritage and is open to the public. The castle until recently was the administrative headquarters of the former King’s Own Royal Border Regiment now county headquarters to the Duke of Lancaster’s Regiment and a museum to the regiment is within the castle walls.
