One of the four royal archives of the Joseon Dynasty is located on the Odaesan. It was founded in 1606 to house the Annals of the Joseon Dynasty and Uigwe or Royal Protocols of the Joseon Dynasty. All but one of the Joseon archives were burned during the Japanese invasions of Korea. Although the Annals themselves were removed in the early 20th century and taken to Japan, where they were lost in the Great Kanto earthquake, the archive has been restored.
