It is considered one of the best-preserved examples of an earthen fortress from the early Three Kingdoms period.
The four-gate system was strategically placed at the center of each wall, unlike many other fortresses that offset gates for defense.
The fortress was constructed using the 'panchuk' method, where soil is packed into wooden frames to create high-density walls.
The site was historically positioned to control the intersection of the Miho-cheon and Musim-cheon streams.
It is a popular location for filming historical dramas and movies due to its authentic, untouched aesthetic.
The site was designated as a Historic Site of South Korea in 1999.
Jeongbuk-dong Toseong is a rare earthen fortress dating back to the Three Kingdoms period of Korea, likely constructed by the Baekje kingdom. The square-shaped ramparts span approximately 655 meters in total perimeter and were built using layers of rammed earth. Archaeological excavations at the site have unearthed iron arrowheads, pottery shards, and roof tiles indicating its strategic military role. The fortress features four distinct gates situated on each side, a unique architectural layout for earthen fortifications of this era. It serves as an open-air historical site that is not enclosed, allowing constant accessibility. The site is widely recognized for its minimalist profile and silhouettes of zelkova trees against the sky.
Position yourself at the bottom of the embankment looking up toward the solitary zelkova trees silhouetted against the horizon.
Wear comfortable, flat walking shoes as the terrain consists of unpaved dirt paths and grassy embankments.
Bring your own water and snacks, as there are no commercial vendors or convenience stores located within the fortress grounds.
The area is completely exposed to the elements, so bring sun protection in summer and wind-resistant layers during spring or autumn.
Do not attempt to visit after heavy rainfall, as the unpaved paths become extremely muddy and slippery.
Do not climb or walk on the ancient earthen ramparts themselves; stick to the designated paths at the base to prevent erosion.
