Early Communication Signal Fires media type="custom" key="28072581" width="76" height="76"

Signal fires have been used since ancient times for long-distance signaling and communication: often serving the same purpose as lighthouses, warning ships of cliffs, or watchtowers, warning allies or communities of approaching enemies. They were generally large piles of wood, kept ready to be alighted when need be at a given location. Classically, beacons were fires lit at well-known locations on hills or high places, used either as light uses for navigation at sea, or for signaling over land that enemy troops were approaching, in order to alert defenses. As signals, beacons are an ancient form of optical telegraphy, and were part of a relay league. Systems of this kind have existed for centuries over much of the world. In Scandinavia many hill forts were part of beacon networks to warn against invading pillagers. In Wales, the Brecon Beacons were named for beacons used to warn of approaching English raiders. In England, the most famous examples are the beacons used in Elizabethan England to warn of the approaching Spanish Armada. Many hills in England were named Beacon Hill after such beacons. In the Scottish borders country a system of beacon fires were at one time established to warn of incursions by the English. Hume, Eggerstone castle and Soltra Edge were part of this network. In Ancient China, soldiers stationed along the Great Wall would alert each other of impending enemy attack by signaling from tower to tower. In this way, they were able to transmit a message as far away as 750 kilometers (470 mi) in just a few hours.
