California Quadrangle
Why it's listed
Balboa Park's California Quadrangle is a group of Spanish-style buildings and connecting walls near the west entrance to El Prado, reached across the Cabrillo Bridge. Built for the 1915 Panama-California Exposition, which marked the opening of the Panama Canal, it includes the Administration Building, the Fine Arts Building, the California Building and the quadrangle walls linking them. Bertram Goodhue and Carleton Winslow were the architects. The California Building, of reinforced concrete and hollow tile, is crowned by a 200-foot tower with colored tile and a richly sculpted frontispiece honoring figures from California history, carved by the Piccirilli family. The Fine Arts Building, once San Diego's first art gallery, now holds the Chapel of St. Francis, used by the Navy during World War II, and Museum of Man exhibits. The Museum of Man grew from the exposition's physical anthropology displays. The complex was listed for its architecture, art, sculpture and its link to the 1915 exposition. The nomination noted deterioration of the California Building's ornament.
Significance in brief: The complex was built for the 1915 exposition celebrating the opening of the Panama Canal, and the California Building and its 200-foot tower are described as an outstanding example of Spanish baroque reproduction. Architect Bertram Goodhue, called an architect of national significance, master planned the Prado area. The buildings also housed the early Museum of Man exhibits and the Chapel of St. Francis.
