Discover the Roots of California’s Heartland

The San Joaquin County Historical Museum reveals the rich heritage of the region, from the Miwok and Yokuts Indians through Charles Weber (founder of Stockton and first farmer in the area) and the development of modern agriculture. The Museum has eight exhibit buildings and four historic buildings, including the 1848 Weber house and the 1866 Calaveras School. Exhibits include room dioramas of Weber family furnishings, a children’s activity area, and large displays of hand tools and historic agricultural equipment. The 18-acre grounds include the Sunshine Trail living exhibition of native habitats and the Delta Water Path. A Critter Corral of farm animals can be enjoyed weekends from May through August.

What's Happening
Historical Society Offices Closed on Martin Luther King, Jr. Day and on President's Day

The San Joaquin County Historical Society offices will be closed on Monday, January 18, for Dr. Martin Luther King, Jr. Day and on Monday, February 15, for President's Day.


Kicking off the Museum's celebration of its 50th year, the Cortopassi-Avansino Building at the Museum is now filled with exciting new exhibits that portray an era that revolutionized agriculture. The new "Innovators in Agriculture" exhibition features historic equipment, smaller artifacts, historic photos, murals, large-screen videos, and interactive touch-screen displays. The exhibits tell the stories of the families and innovations that developed six crops identified with San Joaquin County after the earlier era of dry-farmed grain: fresh produce "truck farming," dry beans, asparagus, cherries, processing tomatoes, and walnuts.

The building and exhibition were funded by the Cortopassi Family Foundation. Exhibit planning and design were guided by a committee comprised of: Raymond Avansino, Sr., Jerry Barton, Jeff Colombini, Alvin Cortopassi, Del Gotelli, Rudy Mussi, and commitee administrator Julia DiCarlo.
