Imjin Dongnae Uichong is a historical site in Geumgang Park in Busan that holds the remains of people killed during the Imjin War. The graves belong to soldiers, officials, and civilians who died defending Dongnae Fortress alongside Dongnae magistrate Song Sang-hyeon when Japanese forces invaded. In 1731, while Dongnae Eupseong was being repaired, remains of the dead were found at the old south gate site along with round shot and arrowheads. It is designated as Busan Metropolitan City Monument No. 13.
