Sung Sam-Mun is one of the six executed faithful retainers who were opposed to Royal Prince Suyang's attempt to succeed to the throne after deposing his nephew king Danjong. During King Sejong's reign (1418~1450), he made a big contribution to creating Korean script, Hunminjungum, as a scholar of Jibhyeoneon and was killed for keeping his fidelity to King Danjong. In the 2nd year of King Sukjong (1676), Lee Ryang built a shrine near his old house and enshrined six executed royalists. The Government called it as Nokwun Private School, which was renamed as Noheun. Ever since that, every December, memorial ceremony was dedicated to them until Daewongun abolished all the private schools under his private school abolition decree. Later on, students of Confucianism put the mortuary tablet for six and performed memorial ceremony, call it as Noheundan.

In 1954, Hongseong historic site promotion committee renovated the place and performed the memorial ceremony every October 15th on lunar calendar. The previous memorial ceremony site is located about 50km away northeast from this place and historic monument is at the entrance of a town about 30km from here.
