Even if you're not a night owl, cities around Europe offer a compelling reason to stay up 'till dawn.
Back in 2002, Paris kicked off the first White Night, a free, dusk-to-dawn cultural event featuring art, performances, music, and theatre. The event became a phenomenon and now cities around Europe are staging their own annual festivals.
Dates vary by city, and include Riga on August 25, Rome on September 8, Madrid on September 22, Brussels on September 29, and Paris on October 6.
Along the same theme is Long Night of Museums, when museums and cultural institutions in cities around Europe stay open late and the city makes a party of it.
