Samnyeonsanseong Fortress 삼년산성

Samnyeonsanseong Fortress in surrounded by the gorgeous mountains of Boeun County. The area is considered one of the most magnificent spots in Chungbuk Province, which was also the site of many battles during the Three Kingdom Period.

Samnyeonsanseong Fortress was so named because it was completed three years after construction began in 470 A.D. (during the reign of King Jabi Maripgan). The fortress was at the forefront of Silla’s expansion into northwest territories. It was also the site where King Muyeol (654-661 A.D.) welcomed the Dang Dynasty ambassador during the War of the Three Kingdoms.

The sprawling stone-built walls stretch over a mile in length with x_heights and x_widths of 13 and 8-10 meters respectively. The compound still has traces of the north, east and west gate locations which give explanation to ancient theories of fortress construction in Korea.
