Abstract

The Yangju area is located on an important transportation route from the Imjin-Hantan River basin to the Han River basin. Not only is it convenient for transportation in all directions, but the Imjin River and the Han River are located to the south and north, making it advantageous for defense. In addition, due to its natural and geographical advantages, such as having a fertile plain backed by a river, it became a major site of competition during the Three Kingdoms period, and many fortress site remain. Among these, there are 29 ruins where Goguryeo relics have been recovered in the Yangju area. Among them, the Taebongsan Fortress, which is a representative ruin, was examined for various facilities such as earthen and stone walls, castle walls and building sites, and various types of earthenware and relics such as iron armors were excavated. It has been done. Looking at the remains of Goguryeo fortress distributed in the Cheonbo Mountains and Doraksan Mountain and Bulgoksan Mountain surrounding the Yangju Basin, they are largely composed of a ring-shaped outer defense system and a ridge-shaped inner defense system. Among these, the Taebongsan fortress shows an independent form in terms of location compared to the Goguryeo fortifications distributed throughout the Yangju Basin. Among the major transportation routes leading to the Yeoncheon-Yangju-Uijeongbu axis, the Taebongsan Mountain Fortress is centered on Gamaksan Mountain in the north, and the southern neck of the corridor that connects to the Jeokseong area (Horogoruseong Castle and Dangpo Castle) on the northern bank of the Imjingang River through Chiljungseong Castle in the west and Amisong Castle in the east. It is located in Considering the location of the transportation route, it appears that the Taebongsan fortress controlled the route crossing the Imjin River through Chiljungseong, which was divided into left and right sides around Gamaksan Mountain. Looking at this aspect, the main function of the Taebongsan fortress is not to construct a main defense line to block the Silla or Baekje army approaching from the south, but to block the enemy's main attack route from the Han River basin - Uijeongbu and Yangju areas - Imjin and Hantan River basins to the Yangju Basin. It appears to have played the role of monitoring from the rear end of the interior and quickly informing our troops stationed at the Imjin River defense line of the situation of enemies advancing north in case of emergency.
