Alcatraz Island LighthouseEdit profile
Alcatraz Island Lighthouse is a lighthouse in California, United States, on Alcatraz Island in the San Francisco Bay, California. It is the oldest light station on the U.S. West Coast.History
The Baltimore firm of Gibbons and Kelly was awarded the contract to build seven lighthouses in California, at Alcatraz Island, Fort Point, Point Piños, Point Loma, Farallon Island, and Humboldt Bay, and one at Cape Disappointment in Washington State. The Alcatraz Lighthouse was completed in 1853. It was lit in 1854 from a fixed, third-order Fresnel lens. In 1902 it was transferred to the Cape St. Elias Lighthouse in Alaska and replaced by a revolving fourth-order Fresnel lens, producing a white flash every five seconds.
In 1909, the present cell house was built. Since the new structure would interfere with the operation of the lighthouse, a taller 84-foot, concrete tower was built south of the original lighthouse. The original lighthouse, which had been damaged during the 1906 San Francisco earthquake, was eventually torn down. In 1963, the Alcatraz Lighthouse was automated by the United States Coast Guard. In 1970 a fire destroyed the warden's house, the keepers' quarters and other buildings on the island. The only remaining building is the tall cement tower equipped with a modern beacon.Historical information from Coast Guard web site

A federal penitentiary is also on the island. This light is the oldest major navigational light on the West Coast. For over 50 years, the lighthouse survived prison breakouts, riots and burning.
