Description

The west entrance to Braunston Tunnel is a tunnel entrance built in the late 18th century, designed by engineers James Barnes and William Jessop. The arch and flanking walls are made of rendered brick, with the brickwork exposed on the right side of the parapet. There is a rendered string course at the base of the parapet. The tunnel itself is 2,045 yards long and was opened in 1796. The Grand Junction Canal, which includes this tunnel, was authorized by an Act of Parliament in 1793. In 1929, the canal was taken over by the Grand Union Canal Company, leading to a name change.
