As a local official of the Korean Dynasty (1392-1910), the Yamen of Jeju Pastoral Officer had been a government institution during the Tamna Dynasty. In 1434, the existing government office facilities were burned down, and the next year we built the buildings we now see on the site. Throughout the Korean Dynasty, the building structure of the Jeju Pastoral Official Yard has been well repaired and protected. Unfortunately, the Japanese invaded from 1910 to 1945, and all the facilities were razed to the ground. In the 1990s, sponsored by the government of Jeju Island, four excavations were made to rebuild the pastoral government of Jeju to the greatest extent. In the process of excavation, a large number of historical relics dating back to the Tamna period were excavated, and the scale and distribution of the pastoral government in ancient Jeju were also confirmed. Based on these information and historical records, the site was rebuilt in 1999-2002.
