Nuit Blanche
Nuit Blanche (; All-Nighter, is an annual all-night or night-time arts festival. 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.
