The Old Boseong Inn is a Japanese-style two-story wooden building constructed in 1935. Well preserving the characteristics of Japanese wooden architecture, this building was recognized for its significance as a modern architectural heritage site and was designated Registered Cultural Heritage No. 132 on December 31, 2004. Built originally as a practical lodging facility, this building came to be widely known for a reason beyond its architectural value alone.
In Jo Jeong-rae's epic novel The Taebaek Mountains and the film of the same name based on it, this very building served as the real-life model for the "Namdo Inn," where Im Man-su, the commander of the government's suppression forces against the rebel militia, and his soldiers stay. A space where fictional characters from a novel and film once lodged had, in reality, remained standing all along in a corner of Beolgyo. As the years passed, however, this building suffered damage, and it was ultimately purchased by the National Trust of Korea Cultural Heritage in 2008, with restoration work completed in 2011. A building where literary fiction and actual history had overlapped thus gained, in this way, a second life.
