To the delight of nightowls who also have a penchant for lurking around in museums, Paris hosts one night a year where most of the city's major museums open their doors to the public late-- and generally free of charge. Paris Museum Night, or La Nuit des Musées, usually falls in mid-May: perfect at a time when most of us prefer to be outside lounging in the city's verdant parks or roaming around the streets.
