The San Francisco Museum of Modern Art has been the premier West Coast spot for modern art since 1935, with over 27,000 works from Modernists and contemporary artists. Mario Botta's iconic building is a work of art in itself, with an oculus skylight, banded turret, and soaring atrium. SFMOMA exhibits painting, photography, sculpture, architecture, and media arts, including important pieces by well-known artists such as Henri Matisse, Ansel Adams, Mark Rothko, and Diego Rivera. Rotating exhibits feature contemporary artists such as the recent Face of Our Time, which showcased photographs from modern society around the world. In 2013, SFMOMA will launch a three-year expansion, doubling its indoor gallery space—the better to display acquisitions like the Fisher Collection of 20th-century masters.
