Housed in a vast belle époque palace, this oft-overlooked gallery is an unsung gem. Its superlative collection runs the gamut from neoclassical sculpture to abstract expressionism with works by many of the most important exponents of 19th- and 20th-century art.

There are canvases by the macchiaioli (Italian Impressionists) and futurists Boccioni and Balla, as well as sculptures by Canova and major works by Modigliani, De Chirico and Guttuso. International artists represented include Van Gogh, Cézanne, Monet, Klimt, and Alberto Giacometti, whose trademark stick-figures share a room with a Jackson Pollock canvas, a curvaceous Henry Moore sculpture, and a hanging mobile by Alexander Calder.
