Devizes (/dɪˈvaɪzɪz/) is a market town and civil parish in Wiltshire, England. It developed around Devizes Castle, an 11th-century Norman castle,[2] 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.
From the 16th century Devizes became known for its textiles, and by the early 18th century it held the largest corn market in the West Country, constructing the Corn Exchange in 1857. In the 18th century, brewing, curing of tobacco, and snuff-making were established. The Wadworth Brewery was founded in the town in 1875.
Standing at the west edge of the Vale of Pewsey, the town is about 10.5 miles (16.9 km) southeast of Chippenham and 11 miles (18 km) north-east of the county town of Trowbridge. It has nearly five hundred listed buildings, some notable churches, a town hall and a green in the centre.
