Frozen Lighthouse, Lake Erie, North America

History
Ancient
Perhaps the most famous lighthouse in history is the Lighthouse of Alexandria, built on the island of Pharos in Hellenistic Egypt. The name Pharos is still used as the noun for "lighthouse" in some languages, for example: Albanian, Catalan and Romanian (far), French (phare), Italian, Galician and Spanish (faro), Portuguese (farol), Danish, Norwegian and Swedish (fyr), Bulgarian (фар), and Greek (φάρος). The term "pharology" (study of lighthouses) also derives from the island's name.
