忠州地域의 百濟 城郭에 대한 새로운 접근

Abstract

This study aims to reassess previous research on Baekje fortresses in the Chungju region and present a new perspective. First, an overview of the Baekje fortresses distributed along the Namhan River and Dalcheon River systems in the Chungju area was examined. Additionally, archaeological issues requiring reexamination were identified, leading to the discovery of several significant points of contention. Regarding the Tangeumdae Earthen Fortress, it was found that, in addition to the previously known earthen wall (inner fortress) construction techniques, another method involved diagonally cutting the bedrock and stacking soil or stone materials either diagonally or horizontally on the inner side of the fortress. There is also a possibility that this area served as a gate site for the inner fortress. Furthermore, field surveys suggested the potential existence of an outer fortress and a subsidiary fortress beyond the previously known inner fortress. For Jangmisan Fortress, clarifying the relationship between the valley wall and the brazier facility (residential site) is crucial for distinguishing the construction and management periods. To achieve this, a detailed stratigraphic analysis of the earthen and stone walls, as well as the residential sites in the valley through a longitudinal section analysis along the north-south direction, is necessary. Additionally, a comparison with previous excavation results at Jangmisan Fortress is required to summarize the fortress walls’ unique and common characteristics. Jangtaesan Fortress has been recognized as comprising a Baekje earthen fortress at its summit and an outer Goryeo-era fortress. However, this study proposes the possibility that the Baekje earthen fortress may have been a double-walled fortress composed of an inner and outer fortress. Moreover, field surveys confirmed the partial remains of an earthen rampart. Therefore, a more in-depth academic investigation is required for Jangtaesan Fortress. Gyeonhak-ri Earthen Fortress is a rectangular earthen fortress adjacent to a river, making it unique. Notably, the spacing of the embankments may have been altered from the previously known 3.3 meters to a narrower range of 1.5 to 1.7 meters. This indicates the need for a detailed academic investigation to reassess the construction period of the Gyeonhak-ri Earthen Fortress. This study is significant as it proposes new research topics for understanding Baekje’s waterway expansion along the Namhan River, Baekje’s territorial advancement into the Chungju region, and the struggle between Baekje and Goguryeo over control of this area.
