This study is about the Changdeokgung Palace and detached palaces of architect Park Jacheong who was a representative supervisor having framed the palace architecture of the Joseon Dynasty. The results are as follows. First, Park Jacheong had been in charge of Changdeokgung Palace for 15 years since its founding. The palace was continued to run for the longest time and was the palace on the frame made by him for the years, so Changdeokgung Palace’s status has become as good as Gyeongbokgung Palace’s. Second, he built a lot of palaces besides Changdeokgung. They were completed about the same time in accordance with the political intentions of King Taejong. Park Jacheong was a former military officer and was well skilled in mobilization of manpower and materials by making good use of the military power. Third, the detached palaces constructed by him were located in the places where military training and testing of new weapons were possible. They were also used as sleeping, dining and office spaces. This can be regarded as a result of the tradition of the storied-pavilion that had been since the Goryeo Dynasty, with the method of approaching to the main hall of the palace.
