aerial photographs of Barnard Castle including both the town and the castle from which the town takes its name. The Grade I listed Barnard Castle was built at the end of the 11th century by Guy de Balliol. The castle was extended and improved throughout the medieval period and in 1216 held out against besieging Scottish forces. In the 15th century the castle was owned by Richard, Duke of Gloucester who was later crowned Richard III. The Castle was abandoned in the 17th century and the ruins are now in the care of English Heritage.
