Details 742/0/10021 GORDON PROMENADE EAST 17-SEP-10 Barrelled lock chamber, sea walls, swi ng bridge, locks and canal basin II Canal basin, lock chamber, sea wall, locks and swing bridge. 1799-1801 sea wall, lock chamber and canal basin, designed by civil engineer Ralph Dodd. Late-C19 swing bridge and probably C20 lock gates. The late-C20 wooden panelling to part of the western side of the northern part of the canal basin is not included, nor is the late-C20 concrete sheet piling to the western section of the south side of the canal basin, to the western side of the canal basin and part of the western side of the north side of the canal basin. MATERIALS Walls mainly of yellow and brown brick in English bond with deep York stone coping and quoins, in places patched with C20 engineering bricks. The canal basin is reported to have a paved floor. The swing bridge, lock gates and their mechanisms are of cast-iron. There is a wooden floor to the swing bridge and wooden lock gates. DESCRIPTION The River Thames frontage has curved sea walls which lead directly into the barrelled lock chamber, unusual because it has a curved shape, partly to match the shape of ships hulls. The north west side wall has a series of Roman numerals by the locks to indicate the water depth. The extreme north of the north eastern side of the lock chamber has been strengthened in late-C20 concrete and sheet piling. The swing bridge at the northern end is a cast-iron riveted structure with flat arch and cast-iron handrail, still operated by a circular cast-iron winch on a three-legged pedestal. The northern lock gates were blown off by enemy action during the Second World War and not replaced. The southern lock gates comprises two panelled wooden gates, probably of C20 date, with a cast-iron walkway abo
