Housed in the fabulous former residence of the Ukrainian Princess Kotchubey, this fine collection of 19th- and 20th-century art includes works by Rodin and Dufy, as well as works by a dynasty of painters, the Dutch Vanloo family. One of its best-known members, Carle Vanloo, born in Nice in 1705, was Louis XV’s premier peintre. High drama hit the museum in 2007, when armed robbers broke into the museum on a quiet summer Sunday, stealing priceless canvases by Monet and Sisley. The artworks were recovered less than a year later in Marseille.
