Lime Point Light
Lime Point Lighthouse is a lighthouse in California, on the northern side of the narrowest part of Golden Gate strait. The lighthouse sits at the base of a steep cliff, very near the North anchorage of the Golden Gate Bridge. It is built on a long rock spur named Lime Point. History. The brick structure for the Lime Point Lighthouse was built in 1883 as a fog-bell signaling station. It was eventually fitted with coal powered steam whistles. During operation, the facility included the fog signal building, a coal shed, water tank and a two-story  keeper's quarters. The keeper's building was later upgraded to include a third floor. In 1900, a lens lantern was hung on the south-east corner of the fog signal building, at a height of above the water. In 1902, the coal-powered steam horn was modified to use crude oil to reduce operating costs and smoke pollution. Lime Point Lighthouse continued to operate after the completion of the Golden Gate Bridge since it remained an effective position for a light and fog horn, even though Fort Point Light, at the South end of the bridge was decommissioned. Lime  Point was automated by the United States Coast Guard in 1961, and the three-story dwelling and other buildings were torn down, leaving only the fog signal building, which remains.
