built the keep as it was complete by 1164. Following the Siege of Acre in 1191, and as a reward for his service, King Richard I appointed Sir John Forster the first Governor of Bamburgh Castle. Following the defeat of the Scots at the Battle of Neville's Cross in 1346, King David II was held prisoner at Bamburgh Castle. During the civil wars at the end of King John's reign, the castle was under the control of Philip of Oldcoates. In 1464 during the Wars of the Roses, it became the first castle in England to be defeated by artillery, at the end of a nine-month siege by Richard Neville, 16th Earl of Warwick, the "Kingmaker", on behalf of the Yorkists. Modern history The Forster family of Northumberland continued to provide the Crown with successive governors of the castle until the Crown granted ownership (or a lease according to some sources) of the church and the castle to another Sir John Forster in the mid-1500s, after the Dissolution of the Monasteries. The family retained ownership until Sir William Forster (d. 1700) was posthumously declared bankrupt, and his estates, including the castle, were sold to Lord Crew, Bishop of Durham (husband of his sister Dorothy) under an Act of Parliament to settle the debts in 1704. Crewe placed the castle in the hands of a board of trustees chaired by Thomas Sharp, the Archdeacon of Northumberland. Following the death of Thomas Sharp, leadership of the board of trustees passed to John Sharp (Thomas Sharp's son) who refurbished the castle keep and court rooms and established a hospital on the site. In 1894, the castle was bought by the Victorian industrialist William Armstrong, who completed the restoration. During the Second World War, pillboxes were established in the sand dunes to protect the castle and surrounding area from German invasion and, in 1944, a Royal Navy corvette was named HMS Bamborough Castle after the castle. The castle still remains in the ownership of the Armstrong family. After the War, the castle became a Grade I Listed property. The description included this comment about the status of the building in 1952 and its history:Castle, divided into apartments. C12; ruinous when acquired by Lord Crewe in 1704 and made habitable after his death by Dr. Sharpe ... Acquired by Lord Armstrong, who had extensive restoration and rebuilding of high quality by C.J.
