Les Halles is an area of Paris, France, located in the 1er arrondissement. It is named for the large central wholesale marketplace, which was demolished in 1971, to be replaced with an underground modern shopping precinct, the Forum des Halles. It is notable in that the open air center area is below street level, like a pit and contains sculpture, fountains, and mosaics.
Beneath this lies the underground station Châtelet-Les-Halles, central hub of Paris's express urban rail system, the RER.
