The lighthouse was built in 1913 on a breakwater constructed in 1910.","why_significant":"The nomination presents the light as the harbor's landmark and seamark since 1913, tied to the growth of Los Angeles Harbor into a major man-made port. It also points to the unusual engineering of the tower, which has a braced steel frame that allows for realignment as the breakwater settles. The Park Service reviewer's note describes it as locally significant.","narrative":"Los Angeles Harbor Light Station sits at the end of the San Pedro Breakwater, about 2.1 miles west of San Pedro. The lighthouse was completed in 1913 at a cost of $35,971.49. It is a five-story concrete tower on a structural steel frame, with an octagonal first story, a twelve-sided second story and cylindrical upper stories. Its lantern is 59 feet above the pier top. The station carries a green light, a fog signal and a radio beacon. Two support buildings stand nearby: a 1942 quarters building and a 1938 oil house. Storms over the years have tilted the tower slightly toward shore, but its braced frame was designed to be realigned as the breakwater settles. The light has marked the harbor entrance since 1913 and has been a witness to the port's growth. Los Angeles Harbor commissioners present new deep-sea ships with plaques that show the lighthouse. No keepers have lived there since 1971.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"No keepers have been stationed there since 1971, and the domestic equipment has been removed or is unserviceable.
