Point Bonita Lighthouse

Point Bonita Light is a lighthouse at the tip of Point Bonita on the California Pacific Coast. The lighthouse was originally built on a 300 feet ( about 91 meters) situated on the sea rocky plateau in 1855. The light generated by the second-order Fresnel lens had a range of 20 miles, however, was no longer visible in heavy fog. Therefore, the lighthouse was moved in 1872, closer to the water. The second version is now on a narrow point of land about 124 feet ( 37 meters) above the water. It is equipped with the Fresnel lens of the first lighthouse and additional fog horns and in operation since 1877. Since 1981, the light signal is operated automatically; so is Point Bonita Light the last lighthouse on the California coast, which was converted to automatic operation. On weekends, the lighthouse is now open at certain times by a wooden bridge for tourists. On September 3, 1991 Point Bonita Light was listed on the National Register of Historic Places.
