This downtown museum prides itself on its origins: In 1969, the beautiful 19th century building that then housed a library was threatened with demolition, and a group of citizens banded together to save it and open an art gallery. That local effort grew, creating this remarkable downtown facility, including a light-filled wing added in the 1990s. Permanent exhibits present an outstanding and varied collection, including contemporary abstracts, photography, figurative painting, sculpture, and works in new media by Bay Area artists. If you’ve got kids, check the schedule for family-friendly, hands-on activities to help children get excited about art.
