The Musée National d'Art Moderne is the national museum for modern art of France. It is located in Paris and is housed in the Centre Pompidou in the 4th arrondissement of the city. It is among the most visited art museums in the world and one of the largest for modern and contemporary art. In 1937, the Musée National d'Art Moderne succeeded the Musée du Luxembourg, established in 1818 by King Louis XVIII as the first museum of contemporary art created in Europe, devoted to living artists whose work was due to join the Louvre10 years after their death. Imagined as early as 1929 by Auguste Perret to replace the old Palais du Trocadero, the construction of a museum of modern art was officially decided in 1934 in the western wing of the Palais de Tokyo. Completed in 1937 for that year's International Exhibition of Arts and Technology, it was temporarily used for another purpose, since the exhibition of national and foreign art indépendant was then preferably held in the Petit Palais and the Musée du Jeu de Paume. Although due to open in 1939, construction was eventually interrupted by the war; following the nomination of its first Chief Conservator in September 1940, the museum partially opened in 1942 with only a third of the collection brought back from some national collection caches hidden in the province. But its real inauguration didn't take place until 1947, after World War II and the addition of the foreign schools collection of the Musée du Luxembourg, which had been held at the Musée du Jeu de Paume since 1922. In 1947, then housed in the Palais de Tokyo, its collection was dramatically increased by its first director, Jean Cassou, thanks to his special relationship with many prominent artists or their families, such as Picasso and Braque. With the creation of the Centre Pompidou, the museum moved to its current location in 1977. The museum has the second largest collection of modern and contemporary art in the world, after the Museum of Modern Art in New York, with more than 100,000 works of art by 6,400 artists from 90 countries since Fauvism in 1905. These works include painting, sculpture, drawing, print, photography, cinema, new media, architecture, and design. A part of the collection is exhibited every two years alternately in an space divided between two floors, one for modern art, the other for contemporary art, and 5 exhibition halls, on a total of within the Centre Pompidou. The Atelier Brancusi is located in its own building adjacent to the museum. The works displayed in the museum often change in order to show to the public the variety and depth of the collection. Many major temporary exhibitions of modern and contemporary art have taken place on a separate floor over the years, among them many one-person exhibitions. Since 2010, the museum has also displayed unique, temporary exhibitions in its provincial branch, the Centre Pompidou-Metz, in a space divided between 3 galleries and since 2015, in Málaga, Spain, and 2018, in Brussels, Belgium.
