The California Quadrangle is shown during the Panama-California Exposition of 1915. The Exposition was held in San Diego's Balboa Park to celebrate the completion of the Panama Canal. The Quadrangle connects the California Building on the north side of El Prado street to the south side. The Plaza de California is in the center of the quadrangle, with the Fine Arts Building seen on the left behind the red tile roof. This building is part of the San Diego Museum of Man in 2020.
