The Old Point Loma Lighthouse stood watch over the entrance to San Diego Bay for 36 years. At dusk on November 15, 1855, the light keeper climbed the winding stairs and lit the light for the first time. What seemed to be a good location 422 feet above sea level, however, had a serious flaw. Fog and low clouds often obscured the light. On March 23, 1891, the light was extinguished and the keeper moved to a new lighthouse location closer to the water at the tip of the Point.
