삼국통일의 교두보, 삼년산성 (KBS_2000.08.19.방송)

◼︎ Located in Boeun County, North Chungcheong Province, Samnyeonsanseong Fortress is a slate-built mountain fortress completed in the late 5th century. Its construction took three years, hence its name. It's often said that planting a tree requires ten years of planning, and raising a person requires a hundred. Silla unified the Three Kingdoms 200 years after constructing this fortress. While Samnyeonsanseong Fortress alone didn't accomplish the great feat of unifying the Three Kingdoms, it certainly played a crucial role in the process. We will examine the topography and construction method of Samnyeonsanseong Fortress, as well as the reasons for its construction in Boeun, and analyze its contribution to the war of unification. #KoreanHistory #History #HistorySpecial #HistoryJournal Copyright ⓒ KBS.
