Part 7/10:
Located in Galicia, Spain, the Tower of Hercules stands as the oldest operational lighthouse in the world, guiding sailors safely for two millennia. Built in the 2nd century AD, this architectural marvel operated using a spiral ramp that allowed fuel to be transported to maintain the beacon.
Despite renovations to its exterior, the original structure remains intact, testifying to Roman engineering prowess. The principles used in its construction – height, visibility, and strategic placement – are still relevant to modern lighthouse designs, ensuring maritime safety amid changing technologies.
