"La Nuit des Musées" (Long Night of the Museums) on Saturday, May 21st, will see museums and other cultural sites including castles open late to the public - the vast majority free of charge.
Over 1,200 museums are participating, 150 in Paris alone, with behind-the-scenes access to the exhibits as well as events including workshops, dances and family-friendly activities at numerous sites.
Many tourist favourites are among them, including the Louvre, the Centre Pompidou and the Palace of Versailles where there will be equestrian shows. The Musee d'Orsay will host a big band, while there will be a ball at the Immigration Museum.
But it's not just the capital that gets to join in; there's plenty going on up and down the country too. Visit the official website to see what's happening near you.

Most sites are keeping their doors open from 6pm until midnight, but if there's a particular show or exhibit you want to see, be sure to check the programme here.
You can try to pack in several museums or focus on seeing all the exhibits in your favourite spot, but bear in mind that public transport and the bigger museums will likely be most crowded at the start and end of the evening.

Yes, there will be queues. But it will be worth it for the extra effort the museums put on during this evening with performances, temporary exhibitions, and interactive activities.
The Long Night of the Museums is a Europe-wide initiative now in its 12th year.
