Possibly the most interesting thing about Glasson Dock is that it is still a working commercial port. Despite being situated several miles up the narrow, twisting and tidal River Lune and despite the proximity of much bigger ports such as Heysham it still handles regular seagoing commercial traffic.
Ships don't actually enter the old dock any more but are unloaded (I think it's all inbound trade) on the river quay - a most unexpected sight in these days of mega-docks and container ships.

The port of Glasson was originally developed to replace that at Lancaster, four miles further upstream, but even with a direct canal link and an available disused wharf in the city centre it is, sadly, too much to hope that goods will ever be taken to the city by water again.
