Yongsan Garrison
Yongsan land had traditionally been the site of military facilities under former Korean kingdoms. In 1882, Qing troops used it during the Imo Incident. During those times, Korean and Japanese garrisons were on the outskirts of the city in mostly undeveloped land. The Imperial Japanese Army originally created it as a garrison and from 1910 to 1945 it served as its headquarters. Since then, the city of Seoul has spread, to envelop Yongsan Garrison.
