Balboa Park (San Diego) failed and is scheduled for completion in 2019. El Prado, a long, wide promenade and boulevard, runs through the park's center. Most of the buildings lining this street are in the Spanish Colonial Revival architecture style, a richly ornamented mixture of European Spanish architecture and the Spanish Colonial architecture of New Spain-Mexico. Along this boulevard are many of the park's museums and cultural attractions, including the San Diego Museum of Man, the San Diego Museum of Art, the Museum of Photographic Arts, the San Diego Art Institute, the San Diego Model Railroad Museum, the San Diego Natural History Museum, the
Balboa Park (San Diego) uniforms, and much of the park was filled with plantings of exotic plants. Over 40,000 red Poinsettia plants, all in full bloom, were used. The event attracted the national attention organizers had sought. Even Pennsylvania's Liberty Bell made a brief three-day appearance in November 1915. The event was such a success the fair was extended through 1916. Over the two years, it drew more than 3.7 million visitors, including Henry Ford, William Jennings Bryan, Thomas Edison, Theodore Roosevelt, and William Howard Taft. The expo actually turned a slight profit, which was donated to the San Diego Museum in the park.
