Gwangju National Science Museum

Gwangju National Science Museum is the southwestern Korea regional branch of the National Science Museum network, with permanent halls covering basic physics-chemistry-biology, regional geological and ecological context (the Yeongsangang river basin, Mudeungsan volcanic geology), Korean traditional science (Gwangju-area Joseon-era astronomical observations and weather monitoring), and modern science-and-technology development. The on-site planetarium and 4D theater run scheduled shows daily, and a substantial outdoor exhibition area includes interactive scientific installations that work particularly well as a families-with-kids stop. Free entry to indoor halls (planetarium and theater ticketed with modest fees). Allow about 3 hours for a family visit; solo visitors can cover the essentials in 2 hours. Bilingual signage on the main permanent galleries. Pair with the broader Gwangju cultural attractions — the Asia Culture Center (a major nationally significant modern-culture complex on the site of the former Provincial Hall), the May 18 National Cemetery (the 1980 democracy movement memorial site), and Mudeungsan National Park's foothills for a coherent Gwangju cultural-and-nature day. Weekday mornings are the quietest window; weekend afternoons draw substantial family crowds.
