Scarborough Castle Richard I
While Richard I (reigned 1189–1199) had spent nothing on the castle, his brother King John (reigned 1199–1216) ensured that it was a comfortable residence for himself and his retinue.
John’s rule was strongly opposed by the northern barons, so the castle at Scarborough was fortified as a strategic stronghold. John visited the castle four times during his reign, and spent a considerable sum on the castle.He built the curtain wall on the west and south sides during 1202–1212, and a new hall called the “King’s Chambers”, later Mosdale Hall. In total, John spent £2,291, three shillings and fourpence on the castle. This included £780 that was earmarked for repairing the roof of the keep in 1211–1212. John spent more on the castle than any other monarch. The Pipe Rolls, records of royal expenditure, show that John spent over £17,000 on 95 castles during his reign spread, and Scarborough received the most investment.
