National Children’s Science Center, Science museum in Waryong-dong, South Korea

The National Children's Science Center is a museum in Waryong-dong featuring interactive exhibits and hands-on activities for young visitors. The spaces are designed so children can discover scientific principles through direct experimentation and exploration.

The science museum opened in 1927 in the former Japanese Government-General building. It was renamed the National Science Museum in 1945, destroyed in the Korean War in 1950, and reopened at its current Waryong-dong site in 1962. In 1990 it became the National Seoul Science Museum under the National Science Museum, and after a 2015–2017 renovation it reopened as the National Children's Science Center on 21 December 2017.

The center's three permanent zones are named in Korean: the Sensory Playground, the Imagination Playground and the Creation Playground. Each is organized around a different activity, from sensory play to observation and experiments to creative making, so the visit follows a sequence of play, inquiry and creation.

The center stands at 215 Changgyeonggung-ro in Jongno District, about a ten-minute walk from exit 4 of Hyehwa Station on subway line 4. A gate called Science Gate links the grounds directly with Changgyeonggung Palace. The building reopened in December 2017 after a two-year renovation, so its three permanent halls are laid out for young children.

The museum features special zones where children conduct their own experiments using age-appropriate equipment. These areas differ from traditional museums because hands-on exploration is the main focus rather than observation.
