Abstract
The exact timing, purpose, and nature of the construction of Chimgwaejeong have not been well known about the needle thread. Looking at the transition process of Chimgwaejeong, 1870 and 1926 are important inflection points. The appearance before 1870 is presumed to be a left-right symmetrical floor plan in the center of the three-compartment room in the center of the room in the plan, as it has a left-right symmetrical elevation around the center of the room in the case of elevation. It is believed that it was changed to a four-compartment floor plan during the overall reconstruction in 1870. However, there is an important clue that the original shape was restored in 1926, and it is presumed that the current four-compartment room plane remained the same, the walls of the rear compartment disappeared, and the floor was installed. After that, there was no significant change until the 1950s, and it seems to have been changed to the shape of a government office such as Yeonmugwan during the renovation in 1970 and reached the present day.
