Abstract

Chungcheong Navy Headquarters fortress, located in Soseong-ri, Ocheon, Boryeong, was built along ridges and valleys, and is located deep inside the Cheonsu Bay with a depth of about 20m. It was one of the three major naval bases during the Joseon Dynasty and was responsible for the defense of the Yellow sea coast. According to historical records, the fortress was installed before the middle of the 15th century, and after the construction of the wall in 1510, it will be fully structured. In the early 18th century, the north gate and military archive were newly built, and there are records of continued renovation and repairs of facilities in the fortress until the 19th century. Chungcheong Navy Headquarters fortress was the 3rd largest Navy Headquarters Fortress in the Joseon Dynasty and served as a defense against Japanese invasion. The research on Chungcheong Navy Headquarters fortress was focused on the history, operation, and changes in function. In this study, the structure and construction period of the defense facilities were reviewed through the results of the excavations conducted until recently. Currently, Chungcheong Navy Headquarters fortress has been excavated eight times. As a result of the excavation, a number of building sites, such as pavilions and government offices, were identified inside the fortress. As a result of excavation, a number of building sites such as pavilions and government offices were identified inside the fortress. In addition, defense sites such as walls, fotress gates, fortress with the convex-form of walls for defense (Jeokdae(敵臺) and Chiseong(雉城)), and external defense facilities (sloped walls, moats, and pit traps) were investigated from the outside of fortress wall. As a result of the excavation of the wall facilities and the defense facilities outside the wall, the structure that was first constructed in Chungcheong Suyeongseong Fortress is confirmed, and structures that have been reconstructed and repaired afterwards are confirmed. The substructures and artifacts of the fortress walls are similar to the time when the first construction of the historical record was made. It is understood that the structure renovated and contracted after the Imjin War, identified in the convex-form of walls for defense and external defense facilities, prioritized the importance of defense facilities and the limitations of human and material resources over the construction rules of historical records. And it is judged that the appropriate construction method was applied according to the geographical conditions and environment in which they will be built. Chungcheong Navy Headquarters fortress is being discovered in the long term, and it is expected that a lot of data can be accumulated. In the future, the results of excavation of Navy Headquarters fortress are expected to provide important data for historical interpretation of the coastal military system during the Joseon Dynasty.
