Forum les Halles
Open daily from 9am to 7pm. In the late 1960s what was Paris' primary farmers' market moved out to the suburbs to be replaced by a park above ground, and a sprawling underground shopping centre below. The interior design is strikingly period think Logan's Run. The place is showing its age now, but still draws nearly a half-million parisien/ennes per day, mostly teenagers. There's a movie theater and a media library too.
