What is it about an old federal penitentiary that's so appealing to tourists? Alcatraz beat out the Golden Gate Bridge, the Lincoln Memorial and the Statue of Liberty to be selected the No. 1 landmark in the U.S. in TripAdvisor's recent Travelers' Choice awards.
It also ranked as the seventh most popular landmark in the world, between the spectacular cathedral in Milan, Italy (No. 6) and the Christ the Redeemer statue in Rio de Janeiro (No. 8).
For tourists, Alcatraz isn't just one thing, either. The island in San Francisco Bay holds the first lighthouse built on the West Coast. The original went up in 1854, but was destroyed in the 1906 earthquake. The new one with a concrete tower was completed in 1909 and automated in the 1960s.
It also appeals to birdwatchers (cormorants and gulls nest there) and those interested in seeing the old cells and buildings when it was used as a penitentiary from 1934 to 1963. Alcatraz opened to the public a decade later under supervision of the National Park Service.
