Grand Sluice is 250

'Grand Sluice - Something to Boast About' lecture - by local historian and industrial archaeologist Neil Wright at the Guildhall at 2pm on Saturday, October 8.

Boston's Grand Sluice, 250 years old this month (October), was the Boston Barrier of its day, designed and built by the foremost engineers of the age. If you want to find out more about this iconic structure you can attend a lecture - Grand Sluice - Something to Boast About - by local historian and industrial archaeologist Neil Wright at Fydell House at 2pm on Saturday, October 8. Charge £3 for members, £4 for non members (includes refreshments). All welcome.

A plaque and a new information board will be unveiled by the Lord Lieutenant of Lincolnshire, Mr Toby Dennis, at Grand Sluice at 10.15 am on Monday, October 10. The board will tell the story of Grand Sluice and its importance for flood defence, land reclamation, navigation and the industrial expansion and dramatic population growth of Boston.

In the true no-limits British engineering style of the day Grand Sluice was not built on the river. It was built on a green field site and then the river was brought to the sluice - diverted from its original course, tamed and canalised. Today houses occupy the wide and meandering course of the old river in the Fydell Street, Orchard Street and Castle Street areas. Most of Witham Way Country Park has been developed on one of the widest former stretches of river and marsh.

Boston Borough Councillor Richard Austin has led the Grand Sluice 250th anniversary group. He said: "We couldn't let this important date in the history of one of Boston's most important developments pass by without notice."

It is possibly the earliest surviving tidal outfall sluice still in a substantially original state, and it continues to serve its original purpose.

On Monday, October 3, the Institution of Civil Engineers, will also present a lecture about Grand Sluice by Mr Wright. His talk will describe the engineering challenges the project faced and its impact on Boston and the surrounding fens. This lecture, beginning at 6.15pm at the White Hart is free, but places must be booked at
