Sungkyunkwan, one kilometer north of Seonjukgyo bridge is a representative traditional educational institution in Kaesong. It was founded in the neighborhood of Gukja-dong with the name Gukjagam (국자감; 國子監) in 992 during the reign of King Seongjong of Goryeo, which ignited Korean Confucianism. Its name was changed to Gukhak (국학; 國學) in the reign of Chungnyeol of Goryeo and was referred to as "Seonggyungwan". In 1367, the 16th year of Gongmin of Goryeo's reign, the structure was revamped and Yi Saek, and Jeong Mong-ju, Confucian scholars of the time taught there as professors. In 1592, the 25th year of Seonjo of Joseon's reign, Kim Yuk reconstructed the institution which was burned down by the Japanese during the Japanese invasions of Korea (1592–1598).
