The Fondation Le Corbusier is a private foundation and archive honoring the work of Le Corbusier. It operates Maison La Roche, a museum located in the 16th arrondissement at 8–10, square du Dr Blanche, Paris, France, which is open daily except Sunday. The foundation was established in 1968. It now owns Maison La Roche and Maison Jeanneret (which form the foundation's headquarters), as well as the apartment occupied by Le Corbusier from 1933 to 1965 at rue Nungesser et Coli in Paris 16e, and the "Small House" he built for his parents in Corseaux on the shores of Lac Leman (1924). Maison La Roche and Maison Jeanneret (1923–24), also known as the La Roche-Jeanneret house, is a pair of semi-detached houses that was Le Corbusier's third commission in Paris. They are laid out at right angles to each other, with iron, concrete, and blank, white façades setting off a curved two-story gallery space. Maison La Roche is now a museum containing about 8,000 original drawings, studies and plans by Le Corbusier (in collaboration with Pierre Jeanneret from 1922 to 1940), as well as about 450 of his paintings, about 30 enamels, about 200 other works on paper, and a sizable collection of written and photographic archives. It describes itself as the world's largest collection of Le Corbusier drawings, studies, and plans. In 2016, seventeen of Le Corbusier's buildings spanning seven countries were identified as UNESCO World Heritage Sites, reflecting "outstanding contribution to the Modern Movement". Le Corbusier's portrait was featured on the 10 Swiss francs banknote, pictured with his distinctive eyeglasses.
