Photo of El Prado pedestrian walkway at Casa del Prado, looking west toward the California Tower. Completed in 1971, Casa del Prado is a modified reconstruction of the largest of the temporary exhibition halls built for the 1915-16 Panama-California Exposition. It was named the Varied Industries and Food Products Building, and later renamed the Food and Beverage Building. It is now home to many organizations and activities and has a number of venues that can be rented for events.
