Chilgok Gasansanseong Fortress and Gasanbawi Rock 칠곡 가산산성 및 가산바위

Gasansanseong Fortress (가산산성) in Chilgok-gun, Gyeongsangbuk-do is located in the middle of Chilgok-gun, between Daegu Metropolitan City and Gumi. Mt. Gasan (901m in elevation) is 10km west of Mt. Palgongsan. Because it boasts seven peaks, the mountain was called, ‘Chilbongsan.’ After enduring large wars including the Imjinwaeran (Japanese invasion of Korea in 1592) and the Byeongjahoran (Chinese invasion of Korea in 1636), the Joseon rulers built a fortress over the course of 100 years in the mid Joseon period to aid in Korea’s defense. It is Korea’s only three-layered fortress, consisting of inner, outer and central walls. The flat Gasanbawi Rock (가산바위) at the mountain’s peak, which is large enough to accommodate 100 people at a time, offers a great view of Daegu Metropolitan City.
