The same thing happened to Covent Garden in the 1970s - the original site was closed, a new one was opened that over time became very evidently much better suited to being a large scale wholesale fruit and vegetable market.

Everybody and their uncle bitched and moaned about it, but I think there are few people today who would argue that London would be better off if Covent Garden was still the central produce market rather than the touristic hellhole it is today.

But they're not opening a new one! They're closing the current one and telling the traders to fuck off somewhere else
