Sunk beneath the site of the famous Les Halles markets, swept away to the suburbs in 1969, this modern shopping mall offers the usual run of boutiques, cinemas and restaurants, plus some alternative diversions including the Parc Oceanique Cousteau (Niveau 3) with a variety of hands-on displays and videos; an outpost of the Musee Grevin waxworks (see below); the Musee de I’Holographie; a children’s play area, the Jardin d’Enfants; and the garish Rock’n’Roll Hall of Fame.
