World’s Prettiest Lighthouses

Fire was used as alarm at the edge of water to warn ships and boats of dangerous shores and rocks before electricity. Lighthouses originally relied on lamps as a source of light. Until 1822, a Frenchman called Augustin Fesnel invented the first modern lighthouse lens using prisms while the early light could be invisible in a few miles. The lens by Fesnel could light up in both parallel rays and horizontally. Since then, Fresnel lenses have brought dramatical changes in all lighthouses. Nowadays, lighthouses are seen not only the simple beacons for ships and boats, but they become artworks or stunning sculptures in real life.
