Nuit Blanche (literally White Night, All-Nighter or Sleepless Night in French) or Light Night is an annual all-night or night-time arts festival. Its exact beginning is disputed between Paris, St Petersburg, and Berlin, but, taking elements from all of these, the idea of a night-time festival of the arts has spread around the world since 1997, taking hold from Rome,Toronto to Tel Aviv and Lima to Leeds. A Nuit Blanche will typically have museums, private and public art galleries, and other cultural institutions open and free of charge, with the centre of the city itself being turned into a de facto art gallery, providing space for art installations, performances (music, film, dance, performance art), themed social gatherings, and other activities.
