text: The town was formerly a port; from 1705, horse-drawn lighters transported grain to the numerous water-mills, locally made bricks, coal and even coconuts used for mat-making in Sudbury and Long Melford. Cargos, such as hay and straw, were transhipped in the River Stour estuary at Mistley into Thames barges for transport to London for the horses; they brought back horse-manure for the wheat and barley fields that lie on both sides of the river. During the Great War of 1914–18, and fearing German invasion, the remaining fourteen Stour Lighters were scuttled in Ballingdon Cut. One of these was raised and completely rebuilt by the Pioneer Trust in Brightlingsea. It was delivered, fitted with electric propulsion, to the River Stour Trust in 2012.

  The Canadian city of Greater Sudbury, Ontario (formerly known as Sudbury and still referred to as Sudbury in everyday usage) was named after Sudbury, becoming a settlement in 1883 following the discovery of rich nickel and copper ores there during the construction of the Canadian Pacific Railway. The superintendent of the railway construction project James Worthington was married to Caroline Hitchcock, a woman who had been born in Sudbury, Suffolk, and the name was chosen to honour her.
