This lighthouse, built in 1854, was one of the first eight lighthouses on the Pacific Coast. It continued in use until 1891, when the new Pelican Point Lighthouse began operating. The Point Loma Lighthouse became the site of the Cabrillo National Monument in 1913. During World War II, the Navy used it as a signal tower. Restored by the National Park Service in 1984, it remainsa as a reminder of contribution of 19th century lighthouse keepers and their families to California's maritime past.
