Whitney Museum of American Art

Not necessarily one of the top visited museum in NYC, the Whitney offers an unparalleled collection of American art. Built with 63,00 square feet you'll find works by Georgia O'Keeffe, Mark Rothko, Edward Hopper, and Jasper Johns along with a fantastic rotating exhibit. In even numbered years you can enjoy the Whitney Biennial which shows (very) contemporary art.

The Guggenheim

The unusual building, designed by architect Frank Lloyd Wright is probably more famous than the artwork within, however inside you will find art by Picasso, Monet, Van Gogh, Degas, Pollock, and Kandinsky as well as some surrealist work.
