Looking up from the bottom of the spiral staircase, in the Old Point Loma Lighthouse tower, you can see the ladder that leads to the Lantern Room at the top. Every night, the lighthouse keeper would climb these stairs to illuminate the lamp, and help ships to safely navigate their way along the coast. This lighthouse, near San Diego, CA, was decommissioned in 1891, but has remained a popular sightseeing destination, and is now part of the Cabrillo National Monument.
