Gasansanseong Fortress in Chilgok-gun, Gyeongsangbuk-do is located in the middle of Chilgok-gun, between Daegu Metropolitan City and Gumi. Gasansan Mountain (901m in elevation) is 10 kilometers west of Palgongsan Mountain. Because it boasts seven peaks, the mountain was called Chilbongsan Mountain. After enduring foreign invasions, including the Imjin War (1592-1598) and the Qing invasion of Joseon (1636), the Joseon rulers built a fortress over the course of 100 years 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 at the mountain’s peak, which is large enough to accommodate 100 people at a time, offers a great view of Daegu Metropolitan City.
