Bury St Edmunds is built in a valley carved out by two small rivers – the Lark and the Linnet, both chalk streams that date from about 8000 years ago. Both rivers meeting the centre of Bury and are tributaries of the River Great Ouse which flows to the sea at the Wash in Kings Lynn.
The River Lark, the larger of the two rivers, rises to the south of Bury St Edmunds near Bradfield Combust while the River Linnet rises in Ickworth Park, south west of the town.
Although small rivers today, both have shaped the present day Bury St Edmunds and indeed aided the growth of the town by providing early transport for building and goods for the markets as well as supporting local industries. Old water meadows exist in parts of the town. They were flooded early in the season to provide lush grass for cattle and to prevent the town from being flooded.
The Lark and Linnet Trail follows the two rivers and takes you around the town through a thousand years of history. Each bollard gives a snapshot of the history of the town and follows a water theme as well as showing pictures of the local flora and fauna.
