Mongmyeoksan Beacon Hill Site was constructed to warn the city of incoming enemy invasions and to transmit news of emergencies to the government in Seoul. The name means “beacon hill in the capital.”
During the Joseon Dynasty, a system of beacons were set up which allowed long distance communications. Fires and smoke emitted from the beacons alerted local people in the area and the military that an enemy was approaching.
During the day smoke signals were used to transmit messages. During the night, fire signals were used.
Mongmyeoksan Beacon Hill Site, one of five stations on Namsan, was rebuilt in 1993 using blueprints from geographer and cartographer, Kim Jeong-ho.
