渤海 宮闕構造의 系譜에 대한 檢討 - 上京城과 西古城의 宮殿址을 중심으로 -

Abstract

The publication of the reports on Sanggyeongseong Castle[上京城] and Seogo Castle[西古城] contributed to enhancing the level of studying a step higher on the basis of existing excavation fruits in Old Japan times. Especially, a lot of points of view presented in the reports will be a milestone to understanding the traits of Balhae[渤海] royal palaces. But the recognition revealed here on Balhae royal castles, especially on the genealogy of palaces, have to be examined, compared with the existing studies. It is because discusses on reports were based on the results of the investigation about excavation, but it’s not far from the existing recognition, at the point of view after examination. They said that the structure of Sanggyeongseong Castle found now is the latest shape, but the structure of the past was the same as that of Seogoseong Castle. From an aspect it seems to be reasonable. But, basically that opinion is set out that the palace1 and palace2 of Sanggyeongseong Castle can not be built without the affection of Tang[唐]. This thesis and the another one written by myself found out that there were more parts that could be compared with the arrangement and structure of Goguryeo[高句麗] Palaces than the parts that could be compared with the arrangement of Tang directly. This thesis could establish a direct genealogy from a central palace building division. That report intended to restore the expansion courses of Sanggyeongseong Castle through the recognition on soil layer sections of Sanggyeongseong Castle No.3 palace site. But, compared with restoration height of Seogoseong Palace No.1, object of comparison, it has something to considered on. In addition, the control works for setting main sticks and foundations on the upper parts in the course of piling up soils and stones are found from the other archaeological sites such as miruk temple site of Baekje. So, it is necessary to think of the issue in the other aspects. In the end, referring to the palace sites of Sanggyeongseong Palace No.4 and the palace sites of Seogoseong Palace No.2, this thesis looked into the fact that there were a lot of parts to think of due to something more than only the king’s bedroom[寢殿]. It is because an Assembly hall[講堂] sites of Neungsanri[陵山里] temple Sites[寺址] at Baekje[百濟] periods are found, similar to the structure of the building sites of the palace sites. Now, a lot of discussions are on the progress, in relation to Neungsanrisa Site halls. So, the roles of Sanggyeongseong Castle and Seogoseong Castle have to be discussed on again. It has to be considered on, together with the structure arrangements of vice-palace and structure and palace sites in the right and left . This thesis presented the points of view, different from those of the reports, about some parts. There are some possibilities for developed new culture of Tang to be mixed and imported to the building courses of Sanggyeongseong Castle, as time went by . But, it has to be considered on that a lot of parts that Goguryeo’s culture had are found in Sanggyeongseong Castle. It is because the facts are important hints for understanding position and genealogy that Balhae palace has, viewed from the East Asia Castle styles.
