Description

The Wash House Lock is a canal lock built around 1800 and restored in 1971, designed by engineer John Rennie. It features a brick-lined basin with heavy sandstone coping that is rounded and splayed at the upper end. At the lower end, the coping is splayed and ramps down to the east, while the west wall continues down with a steep coped ramp that returns at a right angle to the canal wall. A bridge crosses the lower end of the lock. There are two pairs of timber gates and cast iron winch gear located at the upper end. The Kennet and Avon Canal, of which this lock is a part, was fully opened in 1810.
