Mile Rock Lighthouse

Ruins of Lighthouse Built in 1906

Lighthouse on Pacific Ocean in San Francisco, CA

The Mile Rocks Lighthouse is an old large concrete foundation that now is home to the fog signal that can often be heard echoing near the Golden Gate Bridge. The Coast Guard also operates an automatic aerobeacon at the site. The rock it is perched on sunk the SS City of Rio de Janeiro on February 2, 1901.

On Wikipedia

Mile Rocks Lighthouse is located on a rock about 2 miles (3.2 km) southwest of the Golden Gate Bridge, off of Lands End in San Francisco, California. It was completed in 1906, replacing a nearby bell buoy. The tower of the lighthouse was removed in 1966, the top converted into a landing pad for helicopters, and the light automated. The lighthouse was at one time painted with alternating red and white rings, but as of 2017, the lighthouse is painted plain white.
