These three buildings were part of the Gyeongju-bu Government Office during the Joseon period (1392-1910). The buildings include a magistrate's residence, an administrative clerks' office, and a military officials office. Although the year of their construction is unknown, based on the fact that the buildings appear on a map of the Gyeongju area drawn in the late 18th century, it is presumed that they were built before this time.
