The Forum des Halles sits on the grounds of the famous old market Halles. For more than eight hundred years these grounds served as the central marketplace for Paris. By the late-20th century the city was forced to relocate the hundreds of food stands and cafés to a suburban area called Rungis. The city decided to turn the le trou des Halles (the hole of the Halles) into what we now know as the Forum des Halles. The Forum des Halles is a park at ground level, a large underground mall, and below that, the world's largest underground subway station. Surrounding the Forum des Halls are numerous shops and restaurants.
