Gwanggaeto Stele
Wunü Shan has a long history of human living. In recent years some archaeologists found historical remains and relics on the mountain, some of which date back to the late Neolithic Age, more than 4,500 years ago. Those relics also include weapons and tools which have thousands of years of history. According to the Samguk Sagi, the Kingdom of Goguryeo was founded above the mountain in 37 BC, and the mountain city remained its capital until King Yuri moved it to Gungnae Fortress in 3 AD. In contemporary sources, the city was called Holbon fortress(홀본성) in the Gwanggaeto Stele and Heulseunggol fortress(흘승골성) in Book of wei. During the North-South States Period in Unified Shilla, it was recorded as Jolbon fortress(졸본성).
