The Inwangsan Shelter in the Woods was originally one of the military guard posts built during the January 21 Incident in 1968. The Inwang 3rd Guard Post, which was the soldiers' living quarters (now the Inwangsan Shelter in the Woods), has been transformed into a public rest area by removing the reinforced concrete piloti structure and paneling and reconstructing it with a wooden architectural structure. The shelter offers both coziness and openness with its nature-friendly wooden interior and large panoramic windows that showcase the forest views of Inwangsan Mountain. It has become a popular spot for those seeking rest in nature, attracting not only hikers taking a break but also people looking for a quiet place to read and enjoy a peaceful moment in the forest.
