The Best Museums

Musées Royaux des Beaux-Arts (Royal Museums of Fine Arts; Brussels): The city's premier historical art and modern art collections are together in a single institution, though not exactly under one roof -- you go underground to the modern section. These two museums contain a memorable panoply of art, from some of the finest works of Flemish old masters, such as Brueghel, Rubens, Van Dyck, and Frans Hals, to Magritte, Delvaux, and Permeke.
