![Gold Star Critiquer/Silver Workshop Editor/Gold Note Writer [C: 398 W: 18 N: 426]](http://i1.treklens.com/misc/g-s-g.gif) (2659) | This lighthouse was taken at Alcatraz Island. The discovery of gold in California in 1848 brought thousands of ships to San Francisco Bay, creating an urgent need for a navigational lighthouse. In response, Alcatraz lighthouse #1 was erected and lit in the summer of 1853.
After 56 years of use, Alcatraz lighthouse #1 was torn down in 1909 to make way for the construction of Alcatraz prison. Alcatraz lighthouse #2 (shown in the photo) was located next to the cell house and completed on December 1, 1909. This 84-foot tower of concrete contained a smaller, fourth-order lens. In 1963, the fresnel lens of Alcatraz lighthouse #2 was replaced with an automated rotating beacon. |
