People in Northamptonshire will be able to walk into a drained section of the Grand Union Canal later this month as part of an event organised by the Canal & River Trust.
As part of a five-month maintenance programme, £37,500 is being spent on repairing lock three in Braunston.
The section of the canal is being completely drained and, on January 24 and 25, members of the public will be able to stand inside the drained chamber to see the works taking place to repair the brickwork and restore the lock gates.
Free tours will be available from the Canal & River Trust staff between 10am and 3pm and visitors will be able to ask trust staff about the work and the history of the canal.
Volunteers from the Explorers education team will be organising some activities for young visitors on Saturday as part of the open day and there will be a display of pictures of the canal put together by pupils from Braunston Primary School.
About £920,000 is being spent on the canals in the South East this winter period to restore the historic canal network.
During the next month, the gates at lock three in Braunston will be relined in order to fit correctly within the chamber and the original brickwork will be exposed and repaired.
Neil Owen, waterway manager for the South East waterways at the Canal & River Trust, said: “Our teams work extremely hard over the winter months when the canals are quieter to repair and care for our canal network in time for the busy summer months.
“The opportunity to actually walk down into a drained lock chamber is quite unusual and not one people in the area should miss. If you’d like to come along, please make sure to wear sturdy footwear.”
