Dongdaemun Yeoksagwan is a museum in Dongdaemun History & Culture Park behind DDP, using the former Dongdaemun Stadium site as its exhibition space. It displays materials and excavated artifacts related to Hanyangdoseong, the Training Center site and Hadogam, and Ogan Sumun and Igan Sumun. The artifacts inside and outside the exhibition hall can be viewed in about 15 to 30 minutes. Because of its small size, it leaves something to be desired as a full-day itinerary.
