Visited this place with two non-members on a nice sunny morning in Hull
I think it's part of the St Andrew's dock pump house (the indoor photos are from the part to the left of the tower on the first pic), on which there are already a few reports.
Who knew pressure gauges were so interesting?
One for another day..
Thanks for looking,
