Yeomingongsu: Defending the City Together with the People

In 1710 King Sukjong called the capital's people his own children and asked how he could fail to plan for their safety in a war. In 1751 Yeongjo ordered that in an emergency everyone in a household but the old and young would climb onto the city wall's parapets, from officials to men with no post.

You start at a model of the Seoul City Wall, Bukhansanseong and the Tangchundaeseong wall joining them, with a film projected over it. Part two covers the army reforms through manuals, weapons and excavated finds, and one station lets you look out through a gun port from inside the wall. The show also explains that Pyeongchang-dong is named after an army grain store built near Tangchundae, so those hillside mansions and galleries sit on a ration depot.

Entry is free, in Special Exhibition Hall B until 25 October, with a curator's talk at 19:00 on Friday 23 October. Until 30 November the museum opens to 21:00 except Mondays and Thursdays (last entry 20:30).
