El Prado Complex

The El Prado Complex is a historic district in Balboa Park in San Diego, California. The 13 acre complex includes 13 contributing buildings and one contributing structure. Most of the structures were built for San Diego's Panama-California Exposition of 1915–16 and were refurbished and re-used for the California Pacific International Exposition of 1935–36. The original architects were Bertram Goodhue and Carleton Winslow. The area was listed on the National Register of Historic Places in 1976.
