Devizes is a market town and civil parish in Wiltshire, England. It developed around Devizes Castle, an 11th-century Norman castle, and received a charter in 1141. The castle was besieged during the Anarchy, a 12th-century civil war between Stephen of England and Empress Matilda, and again during the English Civil War when the Cavaliers lifted the siege at the Battle of Roundway Down. Devizes remained under Royalist control until 1645, when Oliver Cromwell attacked and forced the Royalists to surrender. The castle was destroyed in 1648 on the orders of Parliament, and today little remains of it.
