It was one of the five major beacon networks in Joseon, known as the 'Gyeong-bongsu', which reported directly to the state's military command.
The beacon system used five different fire/smoke signals: one for normalcy, two for sightings, three for enemy approach, four for enemy border crossing, and five for active engagement.
This specific mound, the East Beacon, acted as the final relay point that received signals from the Mokmyeoksan (Namsan) relay chain before reporting to the Joseon royal palace.
During the Japanese occupation and later urban development, the original structure was largely dismantled, leading to the archaeological investigation and reconstruction efforts seen today.
The location on Ansan provides a unique topographical vantage point that remains largely unobstructed by high-rise developments in the immediate foreground.
Muaksan East Beacon Mound, historically known as Bongsu-dae, served as a critical signal fire station within the Joseon Dynasty's national communication network. The site is situated on the ridge of Ansan Mountain and functioned as the final terminal for the signal route originating from the southern provinces. It relayed military information via smoke by day and fire by night to the authorities at the capital. The current structure is a reconstructed stone beacon tower built to commemorate the defensive history of Seoul. The site offers a direct view of the Inwangsan Mountain ridge and central Seoul, reflecting its strategic importance during the 14th to 19th centuries.
The elevated platform directly adjacent to the beacon mound provides a panoramic view of the Seoul skyline and Inwangsan.
Wear sturdy walking shoes as the path to the summit involves uneven dirt trails and stone stairs.
Bring binoculars to better observe the historical markers and the layout of the beacon mounds.
Combine this visit with a hike along the Ansan Jarak-gil trail for a more comprehensive excursion.
Do not attempt to climb the stone walls of the beacon mound, as the structures are preserved heritage sites.
Maintain a quiet tone as the area is considered a historical monument and a place of reflection for local hikers.
