Yes, although it sounds like Preston has / is / will be at risk from developers that own the land and want to build apartments.

The thing about markets like this is that once they're gone, you can never get them back again. My home town, Wellington, shut down the markets at some point in the distant past and have been trying to restart them in the more recent past to little success (think a bunch of cars parked in an uncovered car park trying to sell vegetables).
