The remains of the building sites with continuous footing have not been a subject of main stream research in Goguryeo archaeology. Since the early 2000s, various excavation survey reports on Goguryeo sites, currently located on China’s territory, have been published and related dataset has increasingly accumulated. However, studies on the
building sites, in particular with contiuous footing, have been limited. This research aims to conduct a comprehensive study on such sites. In this paper, classification of Goguryeo building sites by considering elements such as location of a living floor and daily living facilities, is proposed. The building types are divided into subterranean building sites and overground building sites, depending on location of a living floor. Overground building sites are subdivided based on types of their foundation as follows: one with natural stone foundations; one with contiuous footing one with stone foundations; one with wooden postholes; one without foundations. In particular, the one with contiuous footing type occupies more than half of the total building sites and it can be considered as an architectural characteristics of Goguryeo building sites. Temporal changes of the building with contiuous footing of Goguryeo are identified in terms of the construction techniques and spatial arrangement. As time passed, the size of the building and the intra width of living facilities became smaller. In addition, the earlier buildings with contiuous footing were constructed in China. Later, they had begun to be constructed at the peripheral area and ,in particular, were densely concentrated in the cluster of the Achasan mountain military posts in South Korea. Such changes are assumed to have resulted from the hierarchical change in the building sites. Considering the size of building and excavated goods, contiuous footing
tended to have been used in the large buildings with roof tiles during the earlier phase whereas they were used in smaller buildings without roof tiles during the later phase. Given the fact that the size of buidling is correlated with the amount of labour for construction, it directly indicates the hierarchy of the building. Lastly, the buildings with contiuous footing appeared after the sixth century AD in Baekje and Silla areas, but they are not identical with those of Goguryeo. However, some similar techniques for construction are detected, which increases the possibility that architectural technology of Goguryeo was transmitted to Baekje and Silla.
