This is the fifth in our series in which we ask you to identify where in London this picture was taken and what it’s of. If you reckon you know the answer, leave a comment below. We’ll reveal the answer early next week. Good luck!

Thanks to all those who took a look at our Where is It? for last week and for those who hazarded a guess as to where it may be. There were no correct answers – the picture is actually of part of Old Billingsgate Fish Market down on Lower Thames Street (the fish and statue of Poseidon being clues!). While there has been a market on the site for centuries, it only became particularly associated with fish in the 1500s and the first purpose-built market was constructed on the site as late as 1850. Not up to the job, however, it was demolished and a new building, designed by then City Architect Sir Horace Jones, was built upon the site and opened in 1876. In 1982, the market was relocated to Canary Wharf in the Docklands where it still operates today as the UK’s largest inland fish market.
