The best known landmark in Point Loma is the Old Point Loma lighthouse, an icon occasionally used to represent the entire city of San Diego. (It is sometimes incorrectly referred to as the "Old Spanish Lighthouse"; in fact it was built after California was admitted to the United States.) Perched atop the southern point that creates the entrance of the bay with Coronado, the small, two-story lighthouse was completed in 1854 and first lit on November 15, 1855. At above sea level at the entrance of the bay, the seemingly good location for a lighthouse soon proved to be a poor choice, as fog and cloud within the marine layer often obscured the beam for ocean-going vessels.
