Fort Point Light is a decommissioned lighthouse built on the third tier of Fort Point, which is now directly beneath the south anchorage of the Golden Gate Bridge in San Francisco, California. The lighthouse is at the south end of the narrowest part of Golden Gate strait. It was preceded by two other lighthouses in nearby locations. The present lighthouse was in operation from 1864 until 1934.
