Gowerton Lock is one of four locks on the Penclawdd Canal. It was converted into an air-raid shelter during World War II. The entrance is underneath a lock-tail bridge that stands on waste ground. The dimensions of the lock suggest that Penclawdd Canal boats were about the size of conventional narrow-boats.
