Historical background and construction The fortress was constructed beginning in the year 470, during the reign of the Silla Kingdom, one of the Three Kingdoms of Korea. Its name, which translates to "three-year mountain fortress," is believed to reference either the length of its construction or a significant event related to its establishment. The fortress was strategically built on a mountainous terrain, utilizing the natural topography to enhance its defensive capabilities.

The walls are constructed primarily of locally sourced stone, carefully fitted without mortar, typical of early Korean fortress building techniques. The fortress includes multiple gates and watchtowers positioned to maximize surveillance and defense against invaders. The fortress's layout is irregular, adapting to the mountainous landscape rather than imposing a geometric plan. This organic design reflects the practical military engineering of the time, prioritizing natural barriers and elevation advantages.
