Les Halles de Paris, usually simply Les Halles (The Halls), was Paris's central fresh food market. Located in the heart of the city, it was demolished in 1971 and replaced with the Forum des Halles, a modern shopping mall built largely underground and directly connected to the massive RER and métro transit hub of Châtelet-Les-Halles. The shopping mall welcomes 150,000 visitors daily. (text by Wikipedia)
