The two main purposes of a lighthouse are to serve as a navigational aid and to warn boats of dangerous areas. It is like a traffic sign on the sea. The first known lighthouse was the Pharos of Alexandria, Egypt. The oldest existing lighthouse in the world is considered to be La Coruna in Spain that dates from ca. 20 B.C. A Roman lighthouse is located on the Cliffs of Dover in the UK that was constructed in 40 A.D.
These days, lighthouses are run by machines and remote monitoring. The automatic sensors decide if there is extra moisture in the air, and if so turn on the fog signals. Radio signals are used to communicate with the ships. But when the technology was not so advanced the lighthouses were run by lighthouse keepers.
