Malmesbury is a town and civil parish in Wiltshire, England. As a market town it became prominent in the Middle Ages as a centre for learning focused on and around Malmesbury Abbey, the bulk of which forms a rare survival of the dissolution of the monasteries. Once the site of an Iron Age fort, in the Anglo-Saxon period it became the site of a monastery famed for its learning and one of Alfred the Great's fortified burhs for defence against the Vikings. Æthelstan, the first king of all England, was buried in Malmesbury Abbey when he died in 939.
