Samjeondo Monument, Stone stele in Songpa District, South Korea

The Samjeondo Monument is a marble stele 5.7 m tall, 1.4 m wide and 3.95 m deep, set on a turtle-shaped base (guifu) and topped by a chi-dragon head. Mongolian script is carved on the front left, Manchu on the front right, and Classical Chinese on the back. It now stands in a glass and grey metal protective enclosure on the north-east bank of the west lake of Seokchon Lake, behind the Lotte World tower.

The stele was built in 1639 following a peace settlement between the Joseon kingdom and the Qing dynasty at a crossing over the Han River. Its construction marked the end of a conflict that would shape political relations on the Korean Peninsula for decades.

Koreans call it the "Monument of Shame" (恥辱碑), and it has been a target of protest: in 2007, red paint was sprayed on it reading "철" (withdraw), "거" (remove), "병자" and "370", marking 370 years since the Byeongja War. The Chinese text was composed by Joseon official Yi Gyeong-seok, while the Manchu and Mongolian versions are translations. Until 1895, guards were stationed at the stele pavilion.

The memorial stands in a small area near Jamsil subway station, surrounded by panels with background information. The site can be reached on foot from the station in a few minutes and is accessible at all times.

The stele is 5.7 meters tall, not 4, and is made of marble. In 2007, a man painted "撤" and "370" in red on its face to mark 370 years since the Byeongja War; he was arrested and the stone was repaired by June 15. A bronze plaque showing Injo kneeling before Hong Taiji, made in 1983, was removed as having no heritage value.
