It reflects California's reliance on maritime navigation aids and is the last light station complex completed in California. It is also an intact example of Spanish Revival design, shared in California only with Point Vicente.","narrative":"Anacapa Island Light Station occupies the eastern 40 acres of Anacapa Island, part of Channel Islands National Park, overlooking the eastern entrance of the Santa Barbara Channel. The complex includes a reinforced concrete lighthouse tower holding its original 3rd order Fresnel lens, a fog-signal building, an assistant keeper's residence, service and storage buildings, a power house, oil house, derrick landings, a stairway and a concrete watershed. Landings and the stairway date from 1931, and the buildings from 1932. Most buildings follow the Spanish Revival style, with white stucco walls and red tile roofs, popular in Southern California in the 1920s and 1930s. The station was the last light station complex completed in California, following earlier calls for an island light after a steamer wreck in 1853 and an unmanned skeleton tower in 1912. The original keeper's dwelling was accidentally demolished in 1978, but the remaining buildings are original and retain a high degree of integrity.","period_of_significance":"1932-1940","architect_builder":"Lippman, M.W.","architectural_style":"Mission/Spanish Colonial Revival","criteria":["A","C"],"status_note":"Buildings and structures are described as generally in very good condition with high integrity; the lighthouse still contains its original 3rd order Fresnel lens and still plays a role in navigation.
