Yungongdan is a stone altar in Dadae-dong, Saha-gu, Busan, honoring Dadae Cheomsa Yun Heung-sin, who defended Dadae-po during the Imjin War, and those around him. The site holds Yun Heung-sin's memorial stone and a small park commemorating his younger brother Yun Heung-je and the spirit of the common people, and is Busan Metropolitan City Monument No. 9. From the main road across from the Yua Gyoyuk Jinheungwon, the route up is a climb of 145 steps, with wooden benches placed at intervals along the way. The number of steps makes the climb difficult.
