By 1654 a small open-air fruit-and-vegetable market had developed on the south side of the fashionable square. Gradually, both the market and the surrounding area fell into disrepute, as taverns, theatres, coffee-houses and brothels opened up.[1] By the 18th century it had become notorious for its abundance of brothels. An Act of Parliament was drawn up to control the area, and Charles Fowler's neo-classical building was erected in 1830 to cover and help organise the market.
