El Prado Complex
Why it's listed
Running through the heart of Balboa Park in San Diego, El Prado is a collection of buildings, gardens, plazas and a long concrete bridge created for the 1915 Panama-California Exposition, which celebrated the opening of the Panama Canal. The group includes the Cabrillo Bridge, House of Charm, House of Hospitality, Electrical Building, Botanical Building, Organ Pavilion, Alcazar Gardens, Plaza de Panama, the arcade, the Fine Arts Gallery and the Natural History Museum. Bertram Goodhue served as chief architect, with Carleton Winslow and Frank Allen Jr. designing many of the major pieces. Several structures were meant to be temporary but were saved and reused for the 1935 California Pacific International Exposition, with some alterations. The ornate Spanish Baroque and Mission-style detail still defines the park. The complex was recognized as the surviving 1915 portion of Balboa Park and as a lasting symbol of San Diego's heritage.
Significance in brief: The complex preserves the core of San Diego's 1915 Panama-California Exposition. Many buildings designed as temporary were kept and reused for the 1935 exposition and remain in use. The form calls it San Diego's most famous landmark, and it ties together work by Bertram Goodhue, Carleton Winslow, Frank Allen Jr. and others.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
