The Guardian Mountain and Fortress of Old Yangcheon

Mount Gungsan has carried several different names since the Three Kingdoms period (roughly 1st century BCE–7th century CE), and during the Joseon Dynasty it served as both the guardian mountain and the defensive fortress of Yangcheon County, protecting the lower reaches of the Han River.

Key takeaways

Mount Gungsan was known as Pasan during the Three Kingdoms period, and because a fortress once stood atop it, it was also called Seongsan ("fortress mountain"), as well as Gwansan and Jinsan ("guardian mountain"). Fact The *Annals of King Sejong* (a 15th-century royal chronicle) records that this area was known as Jechapahyeon under Goguryeo, Gongam under Silla, and Yangcheon-hyeon under Goryeo. Fact The Annals also record a stone fortress called Jusanseong north of the county seat — this is the fortress that stood on Mount Gungsan. Fact One story holds that General Gwon Yul, who famously repelled Japanese forces at the Battle of Haengju during the Japanese invasions of 1592–1598, also stationed troops at this fortress.

Precise phrasing

Avoid stating flatly that "Mount Gungsan was a major stronghold of General Gwon Yul during the Japanese invasions." Make clear this is a transmitted story, not a documented fact.
