The Samjeondo Monument (Hanja: 三田渡碑) in 136 Samhaksa Avenue/Samhaksa-ro, Jamsil-dong 47-beonji, Seoul Songpa-gu is a monument marking Joseon Korea's submission to Manchu Qing Dynasty in 1636 after Byeongja Second Manchu invasion of Korea. its original name was Daecheong Hwangje Gongdeok Bi (대청황제공덕비/大淸皇帝功德碑) which means the stele to the merits and virtues of the Emperor of Great Qing. Initially erected at Samjeondo, near the Sambatnaru crossing point of the Han River, it was thereafter buried and erected again several times. It is nowadays designated as the 101st Historic site of South Korea.
Following the siege of Namhansanseong in present-day Gwangju City, Gyeonggi Province, King Injo of Joseon had to surrender and was forced to accept vassal status to the Manchu Empire in 1636. The following year, Hong Taiji, Emperor of the Qing Dynasty, ordered King Injo to put up a monument "in honor of the excellent virtues of the Qing Emperor". In 1639 it was erected at Samjeondo, where the ceremony of surrender had been conducted. Inscriptions were written in Manchu and Mongolian on the front side and in Hanja on the back; they have almost identical contents. The Hanja version was composed by Yi Gyeongseok (이경석/李景奭), and the rest seem to have been translated from it.
Samjeondo, meaning "crossing of the three fields", was located near the Sambatnaru (삼밭나루), a major crossing point of the Han River in early Joseon times. The Sambatnaru way was the shortest route to the stronghold of Gwangju and the southern provinces. It was also the one most often used to visit the tomb of King Taejong Yi Bang-won at the foot of Mt. Daemo in Seoul Seocho-gu.
