Discover what lurks behind the decaying facade of Smithfield.  The General Market and Fish Market at Smithfield have been closed for twenty years awaiting a decision on refurbishment.  However, walk around the area and you will find that the main gates are open again not as a place for selling apples but for the storage of cement as part of the Thameslink refurbishment.  Have a look inside and you will see the remains of the market stalls, the hooks for hanging produce and the wooden offices suspended above the market.   A London market unchanged for maybe fifty years.
