Korea is known for its historical fortresses, with over 2100 confirmed in the South alone. In particular, the Chungcheongbuk-do region is dense with these ancient structures, including the Sangdangseong Fortress in Cheongju, which offers a glimpse into the architectural and cultural heritage dating back to the Three Kingdoms period. The fortress served as a strategic military site and refuge during times of war. Another significant site in Cheongju is CheongNamDae, a former presidential retreat now open to the public, offering fascinating insights into the private lives of Korean leaders. The region also features the transformed former tobacco factory, now a cultural hub known as Cultural Factory, and healing experiences at Chojung Healing Village, showcasing Korea's blend of history, culture, and modern wellness.
