Geumjeongsanseong Fortress (금정산성) is located on the peak of Mt. Geumjeongsan (801.5m) in Busan. Its length is 17,377m, and 1.5m~3m high; it is the largest fortress in Korea.
[Historical Point] : it is presumed to have been built during the Three Kingdoms Era (when Goguryeo, Baekje, and Silla, the three dynasties, were fighting against each other). The present fortress was built in 1703, during the reign of Suk-Jong. It was built after Imjin Waeran (Japanese Invasion of Korea from 1592~1598) to prepare for any further invasions from Japan.
