One of the greatest and most popular collections of modern art, on a par with the Tate Modern in London or Paris's Centre Georges Pompidou. Exceedingly popular so be warned: queues for tickets start early and stretch long. To avoid the crowds, turn up at the door at least a half hour before opening, then take the elevator to the top floor and work your way down. The building is as much a draw as the outstanding collection; possessing arguably the best collection of modern masterpieces world-wide, MoMA houses important art works from Van Gogh, Picasso, Monet, Matisse, Salvador Dalí, Paul Cézanne, Frida Kahlo, Piet Mondrian, and works by leading American artists such as Jackson Pollock, Jasper Johns, Edward Hopper, Andy Warhol, and Chuck Close. MoMA also holds renowned art photography and design collections. In addition to being the crown jewel of modern art museums, MoMA puts on a terrific repertory program in a nicely renovated theater below the museum.
