A nearby plaque reads, "This is the monument of the Jangchungdan, where ancestral rites were held for the many officers and men who died while driving back the Japanese after Empress Myeongseong was killed in the Eulmi Tragedy of 1895. Emperor Gojong created Jangchungdan at Namsoyeong in 1900, constructing the shrine and its auxiliary buildings and erecting this monument. Afterward, memorial rites were also held for the civilians who were martyred during the Eulmi Tragedy, both the civil and military martyrs of the Military Coup of 1882, and the martyrs of the 1884 Military Revolution. This monument stands about 2 meters high. It is a simple structure, the body of the monument standing atop an even, square foundation. It was originally within Yeongbingwan, but was moved here in 1969. The characters of Jangchungdan on the monument were written by Emperor Sunjong, when he was Crown Prince, and the 143-character inscription on the back was written by Min Yeonghwan."
