Yes. The original Alcatraz lighthouse, constructed in 1854, was the first lighthouse built on the US West Coast. The lighthouse served as a navigational aid for over 50 years.
On June 1, 1854, Alcatraz became the first operational U. S. lighthouse on the west coast. The original lighthouse looked like a house with a tower protruding through the middle of its roof. In California, the Battery Point , Point Pinos and the Old Point Loma lighthouses have similar designs.
Alcatraz Island proved to be a huge obstacle in the busy shipping channel of San Francisco Bay. So much so, that the U.S. Government allocated money to construct a lighthouse on the island. The first tower was constructed in 1852, but the third-order Fresnel lens wouldn't arrive until 1854. This made it the first lighthouse to be built on the West Coast.
One of the most famous features of the San Francisco Bay skyline is in serious danger. The Alcatraz Island Lighthouse is decaying and is in critical need of repair. If we don't preserve it now, we will lose this priceless historical landmark and world-renowned tourist magnet.
