The Torrance Historical Society and Museum was founded in 1973, and the Museum opened its doors in 1979. The purpose of the Torrance Historical Society is to promote interest in and education in the history of Torrance and the San Pedro Rancho; to promote historical research in Torrance; to collect, acquire, preserve, conserve and make available records, data, photographs, oral history, and related documents and information bearing on the history of Torrance through the operation of a museum and archives.

The Historical Society's mission includes the promotion of history through a Plaque Program, by placing bronze plaques on significant historic landmarks throughout our community. This program is widely recognized, and has been ongoing for the past 20 years.

The primary fund-raiser and signature event for the Torrance Historical Society is its biennial Fall Tour of Historic Homes - a long-standing tradition in the City of Torrance since 1980. This is held on even years during the second weekend of October. Please see the Events page for a list of current and upcoming events with the Torrance Historical Society.

The Torrance Historical Society also hosts walking tours of Old Torrance (founded 1912) on the fourth Sunday of every month, May - October. The walks feature a variety of historical sites.

Glenn Sakamoto, Creative Director of Sakamoto Design + Brand Strategy, designed the New Torrance Historical Society & Museum Logo in 2007. The logo focuses on the historic bridge over Torrance Boulevard, but also evokes the balanced city concept reflected in the Olmsted design, as well as the greater horizon of California.
