The Central Embarcadero Piers Historic District is a Registered Historic District, consisting of Piers 1, 1½, 3 and 5, and is one of the largest surviving pier complexes along San Francisco's Embarcadero. Pier 39 was first developed by entrepreneur Warren Simmons and opened October 4, 1978. Pier 39 is a shopping center and popular tourist attraction built on a pier in San Francisco, California.
At Pier 39, there are shops, restaurants, a video arcade, street performances, an interpretive center for the Marine Mammal Center, the Aquarium of the Bay, virtual 3D rides, and views of California sea lions hauled out on docks on Pier 39's marina. The marina is also home to the floating Forbes Island restaurant. A two-story carousel is one of the pier's more dominant features, although it is not directly visible from the street and sits towards the end of the pier.
