Smithfield Market is a meat market with 800 years of history. The names of the nearby streets tell you about its many centuries of existing: Cowcross St., Cock Ln. and West Poultry Ave. The market opens at 3 am, so you can visit it right after the most popular, but not the best club in London, Fabric. In case you are not into butchery and clubs, the very building of a Victorian era is definitely worth checking out. Once a month you can join an hour and a half walking tour of the market, which you have to book in advance.
