Sudbury (/ˈsʌdbəri/, Suffolk dialect: /ˈsʌbri/) is a small market town in the English county of Suffolk. It is located on the River Stour near the Essex border, and is 60 miles (97 km) north-east of London. It is the largest town of Babergh district council.
The town’s earliest mention is in 799 AD, when Aelfhun, Bishop of Dunwich, died in the town. The Anglo-Saxon Chronicle records the town as Suthberie (“south-borough”), presumed to distinguish it from Norwich or Bury St Edmunds, to the north. The town is also mentioned in the Domesday Book of 1086, as a market town where the local people came to barter their goods. The market was established in 1009.
