Exploring Gyeongseong Through the Online Special Exhibition

The exhibition presented in connection with the Seoul Museum of History is official content that provides additional context for the period setting. The online exhibition runs from August 14 through December 31, 2026. It is accessible through the “Special Exhibition Online Exhibition” section of the series website.
