Dongdaemun City Wall Park lies to the north of Korea’s national treasure no. 1, Heunginjimun Gate. One of Seoul’s most important landmarks, tourists often visit the gate but are unaware that just a few meters across the road lies a spectacular viewpoint of Seoul’s Dongdaemun area. In ancient Korea, this gate was one of eight main gates along Seoul’s city wall. Heunginjimun Gate is situated on the east side of the outer wall of Seoul Fortress. The main function of this structure was to protect important government buildings.
