Hull's Hidden history

As a city of 730 plus years of age Hull has a lot of history there are two problems a lot of it is either hidden or lost due to things like the Blitz (one example of lost history from the Blitz was the Hull municipal museum on Albion street )

The hidden things

How about the Second Dock office ?
Well I bet few of you known a we had 3 dock offices ( in the days of the town docks , the ones in the city centre ) and I also bet you don't know the second one still stands but where is it?
It is behind Hull college near the discussed dry dock / Original entrance to Queens dock ( Hull's first enclosed dock and at the time the UK largest at 10 acres ) ( also where the Bounty was built )

The site of the first town dock's office latter replaced by the pictured second dock office
