San Francisco Museum of Modern Art (SFMOMA)

This monumental building was Swiss architect Botta's first commission in the United States. Like many of his buildings, it illustrates his interest in the circle and the square. The structure is comprised of stepped-back boxes and a truncated striped cylindrical tower. This art museum is in the middle of the block across from the Yerba Buena Gardens and Art Center.
The zebra stripes of gray and black granite, so prominent in the tower, are repeated at the sides of the entrance and in the entrance columns and piers.

The atrium Galleries are grouped around this central open space. At its highest point a steel bridge crosses the atrium.
