California's Old Point Loma Lighthouse has been active for only 36 years. This is a comparatively short time when compared to other lighthouses. Erected in November 1855, its shortcomings were soon evident. Standing 422 feet at the entrance of San Diego Bay, the lighthouse's beam was hidden by fog and clouds. On March 23, 1891, the lighthouse was closed. Old Point Loma Lighthouse is an integral part of Cabrillo National Monument. It is an exhilarating experience to stand at the lighthouse and see the beauty of San Diego Bay.
