Abstract

Geoje Island is an island located on the southern coast. Geographically, it is very close to Japan, so fortresses were built and defended from an early period, with the Silla stone fortresses such as Dundeokgiseong Fortress, Oksanseong Fortress, and Dadaesanseong Fortress being the most important. It was consecrated first. According to literary records, the time when Silla advanced into the Geoje region was during the reign of King Munmu (A.D. 661-681), and 1 county and 3 counties were established, and it continued until the Goryeo Dynasty. The number and location of counties and counties were maintained without major changes. And on old maps of the Joseon Dynasty, the county names of 1 county and 3 hyeons established during the Silla period were continued and are still passed down as place names. What is noteworthy is that these counties and the Silla Seokchuksanseong Fortress have the same distribution rights. Next, as a result of examining each component to understand the characteristics of the Silla stone fortress in the Geoje region, meaningful commonalities were detected. The exterior walls of the castle are all ‘layered’ and the standards and shapes of the stones used are similar. Additionally, stylobate reinforcement was installed at the base of the outer wall. In addition, the catchment area is clearly confirmed to have the same structure of circular shape and terraced cross-section, and it can be seen that the same ‘correct layering’ construction technique as the fortress wall was applied to the revetment stonework. The excavated artifacts show the simultaneity of construction and operation. Artifacts from the Chochuk period commonly excavated from stone fortresses in the Geoje region date from the early to late 7th century, suggesting that the Silla stone fortresses in the Geoje region were operated synchronically. The above common features represent Silla's fortification mechanism. In particular, it can be understood that from the late 5th century, when the Silla stone fortress first appeared, to the stone fortress on the South Sea coast in the 7th century, not only did fortification technology continuously develop, but a series of fortification systems were completed through standardized and refined designs. . In addition, the Geoje region can also be used as a standard for establishing the date of Silla's stone fortresses in that it corresponds to the construction stage with a time axis of the 7th century. This means that the South Sea coast of the Gyeongnam region appears to have been under the effective control of Silla since the mid- to late-6th century at the latest. However, during the fierce occupation of the Han River basin and territorial expansion such as the annexation of Gaya, fortifications were concentrated, and then reached a certain level of stability. This is because intensive construction projects were carried out at key locations along the southern coast of the century.
