The Five Rise Locks on the Leeds-Liverpool canal at Bingley are currently closed to waterway traffic but have been open to the public this weekend. The locks were built in 1774 and are the steepest lock staircase in Britain. Four of the six pairs of lock gates are being replaced as well as repairs to the lock chamber brickwork. I went along yesterday but hadn't expected a queue of several hundred people patiently waiting to descend into the drained locks, an hour or more queueing didn't appeal to me so I came away. I returned this morning at opening time and joined a queue of around a dozen people (more my kind of queue), but when I left around half an hour later the queue had grown to several hundred people again, I had no idea our industrial heritage could be such a crowd puller!
