PARIS: Thousands of Parisians danced in eerie silence at the Gare du Nord train station and galleries left their doors open all night for the French capital's annual "Sleepless Night" festival.

At the train station, twelve DJs performed for crowds wearing headphones at a special "silent disco" event from Saturday to Sunday. The party-goers could choose from three different music channels, dancing to their own rhythms.

Dancer Clementine Schal said she sees the station "differently now." It's normally used for Eurostar trains to London and trains to other points around France and Europe.

In a reference to UN climate talks that Paris is hosting in December, City Hall hosted an all-night exhibit of 270 colorful blocks representing melting ice. About 130 events were held throughout the city.
