Daesosan Signaling Station, created in beginning of the Joseon Dynasty, was the communication tool that sent messages and news via smoke signals and torchlight. The signaling station, often viewable from afar atop the mountain, sent smoke signals during the day and fire signals by night. The Daesosan Signaling Station was one of numerous provincial signaling stations that informed Namsan Signaling Station in Seoul of the status in the Yeongdeok, Chuksanpo region. From Daesosan Signaling Station either fire or smoke signals pass onto Byeolban Station to the south, Pyeonghae Hurisan Station to the north and Gwangsan Station to the west, and then arrives at Namgaksan Signaling Station. Daesosan, a major mountain in the Southeast coast of Yeongdeok, is 282m above sea level. The top of the mountain has a fortress wall made of stone within which the cone-shaped signaling station sits. Daesosan Signaling Station is a well-preserved example of the communication tools used during the Joseon Dynasty.
