You might not be a fan of museums overall, thinking them boring and not worth the time or money. Well, at least you don't have to think about money if you happen to be in Paris on the first Sunday of a month, as at this time museums are free of charge and have been since 2000. Out of several hundred museums in Paris, there is a few truly unmissable that everyone should visit at least once in their lifetime. These iconic museums include the Louvre, the Centre Pompidou, Musée d’Orsay, Grand Palais and Petit Palais, Cité de l’Architecture et du Patrimoine, Musée du Quai Branly, Musée National du Moyen Age—Thermes de Cluny, Musée des Arts et Métiers, and Musée des Arts Décoratifs. They store invaluable art masterpieces that have lived through ages and are likely to influence the present and future forever. Mind that Grand Palais doesn't partake in the free museum program, yet there is another occasion that allows one to visit Parisian museums for free—this is Nuit des Musées or Night of Museums that has taken place annually on the third Saturday of May since 2006. Not only can you enjoy viewing luxurious exhibitions, but take part in lectures, conferences, debates, and competitions,—and all that for free.
