Before satellites whispered directions from space, a single flame atop a stone tower could mean the difference between home and the ocean floor. Sailors once read the coastline like a story, trusting beams of light to warn them of hidden rocks and shallow reefs in the blackness of night. Each lighthouse had its own signature, a unique pattern of flashes so sailors could identify exactly where they were along the coast. Keepers climbed spiral stairs each evening, tending oil lamps and polishing lenses, guardians of a light that never could be allowed to fail. Fog made the sea blind, so lighthouses spoke in sound too, deep horns and bells echoing across the water like a heartbeat in the mist. Long before satellites traced our paths from above, humans built fire on cliffs and trusted strangers to keep it burning through the night.
