This study is the consideration about Hwaryeong-Jeon that enshrines Joseon Dynasty 22nd king Jeongjo's portrait of a king. Suwon's Hwaryeong-Jeon that accompanied a portrait and performed ritual ceremonies had several formalities and ceremonies which are connected with rituals. therefore, we will try to examine what relation between arrangement of building and plane composition had. And through this, it is thing to observe construction special quality that Hwaryeong-Jeon has. Joseon Dynasty's young-jeon (a hall where the royal portraits are kept) is retaining each other different state according to construction age every moment. Hwaryeong-Jeon among Joseon Dynasty's a hall of royal portraits is the construction form which is equiped well and is known for keeping the form well from the foundation to now And this building is evaluated as the standard form of early part young-jeon building of 19th century. Especially, Hwaryeong-Jeon shows the typical ritual equipments late Joseon Dynasty and at the same time has all kinds of characteristics which only we can find at Hwaryeong-Jeon. Namely, Hwaryeong-Jeon is the building which brings the design concept of the hall of royal portraits to completion as the building which enshrines single portrait of a king. After all, Hwaryeong-Jeon is evaluated as the building which can pass excellent form of late Joseon Dynasty, the hall of royal portraits building just as it is. Therefore, as I study its own style, I expect Joseon Dynasty's mind that enshrined the portrait of a king elaborately to be revealed.
