Dasan Seonggwak-gil is a fortress wall path in Sindang-dong, Jung-gu, Seoul. Walking the Namsan section of the Hanyangdoseong, you can see traces of fortress construction from the 14th to the 16th century of the Joseon period. From Exit 5 of Dongdae Entrance Station on Subway Line 3, a walk of about 100 meters leads to a deck stairway behind Jangchung Arena and the Shilla Hotel duty-free shop. Slopes appear in places, so the path is not entirely easy.
