Founded in 1929, MoMA is one of NYC’s most popular museums, home to more than 100,000 pieces of modern artwork, most by A-listers – Van Gogh, Matisse, Picasso, Warhol, Lichtenstein, Rothko, Pollock, Bourgeois and many others. It’s dedicated to showcasing artwork based on the emerging creative ideas of the late 19th century through to those that dominate today. It’s easy to get lost in the vast collection for an entire day; if you want to maximize your time and create a plan of attack ahead of time, download the museum’s floor plan and visitor guide from the website beforehand. MoMA's permanent collection spans four levels, with prints, illustrated books and the unmissable Contemporary Galleries on level two; architecture, design, drawings and photography on level three; and painting and sculpture on levels four and five. Many of the big hitters are on these last two levels, so tackle the museum from the top down before the fatigue sets in. Must-sees include Van Gogh's The Starry Night, Cézanne's The Bather, Picasso's Les Demoiselles d'Avignon, and Henri Rousseau's The Sleeping Gypsy, not to mention iconic American works like Warhol's Campbell's Soup Cans and Gold Marilyn Monroe, Lichtenstein's equally poptastic Girl With Ball, and Hopper's haunting House by the Railroad.
