Gwollaegaksa was the offices where the Palace’s managerial officials used to work. The Royal Family’s servants and the Palace’s administration officials who looked after facilities of the palace used to be here. The offices do not exist today however, during the Korean Empire period, these offices were present all the way up to the Seoul Square. After the Japanese colonial period, many parts of Deoksugung Palace were turned into a park and many buildings were demolished. Therefore, unfortunately, it is not possible to find traces of these offices.
