Seosaengpo Waeseong Fortress (Seosaengpo Japanese Fortress) is a stone fortress typical of the Japanese style popular in the later part of the 16th century. It was built under the leadership of Japanese General Kato Kiyomasa in 1592-1593 at the beginning of the Imjinwaeran War (Japanese invasion, 1592-1598). The main fortress is located on a mountaintop 200 meters above sea level, a second fortress is halfway down the mountain, and a third fortress is located at the bottom of the mountain. The whole fortress is rectangular shaped. The fortress wall is 6 meters high and slants at an angle of 15 degrees. In 1594, a Buddhist monk named Samyeong-daesa came to Seosaengpo Waeseong Fortress four times to negotiate for peace, but he failed each time. In 1598, the fortress was taken over by Korea with the assistance of General Magwi of the Ming Dynasty. A year later, Changpyodang Shrine was built in honor of the 53 Koreans who died during battles against the Japanese invading forces. However, the shrine was destroyed during the Japanese imperialism period and no trace of it remains. It is possible to tell from Seosaengpo Jinseongdo (a map drawn up in 1872) that the fortress was also partially used by Korean forces.

Cheonjedan are altars set up by people a long time ago to offer goods to Heaven. In old records such as the Samguksagi (History of the Three Kingdoms), there are records that "The Silla Kingdom organized rituals in Taebaeksan Mountain, which it considered as a Bugak Mountain (Northern Mountain, one of the mountains for rituals)." This shows that Taebaeksan Mountain was considered to be a holy mountain in the past. Cheonjedan, or the altar, is situated at the summit of Taebaeksan Mountain. With Cheonwangdan altar in the center, there is the Janggundan Altar in the north and a smaller altar in the south. The altars are built by stacking stones, a sign of a sacred ground. The Cheonwangdan altar is made of natural stone. It has an oval shape and measures 27.5 meters in circumference, 3 meters tall, 7.76 meters wide, and 8.26 meters from front to back. The natural stone is a sort of gneiss, with the upper stone being round and the bottom stone rectangular. Such a form is based on the philosophy of Cheonwon Jibang. In the valleys nearby, there are small or large stacked stone pagodas and stone platforms, which were used for prayers. It is forbidden to kill wild animals or break off tree branches in the area.
