Housed in a Beaux Arts-style building constructed for the 1904 World's Fair, this great museum is a buffet of the arts, where visitors can sample as much as they like of the displays from around the globe and from virtually all time periods. It contains works ranging from ancient and medieval art to European old masters, French Impressionists, American art from 1800 to 1945, and contemporary art. Its pre-Columbian, Asian, and German expressionist collections are ranked among the best in the world (it owns more paintings by Max Beckmann than any museum on the planet). Other galleries feature Islamic and ancient art; an Egyptian collection (including three mummies); arms and armor; media art; and art from Africa, Oceania, and the Americas. There are also displays of Chinese, European, and American decorative arts. You should spend at least 2 hours here.
