Claim this place to tell your story your way.
Built in 1854, it guided ships safely into San Francisco Bay long before the infamous prison was established.
The new structure was built to accommodate the construction of the Alcatraz Federal Penitentiary, which blocked the light from the original tower.
Despite the devastation in the city, the lighthouse remained operational, providing a crucial navigational aid.
Although automated since 1963, it continues to serve as a navigational aid for ships entering San Francisco Bay.
Managed by the National Park Service, it is a protected historic site open to the public for tours and educational programs.
