Namdojinseong

The naval forces and fourth-ranking Manho (navy sub-area commander) at Namdojinseong Fortress had jurisdiction over Jodo Strait and Hauido Island waters off Sinan in order to prevent plunder by Japanese intruders. Today, the former government office, living quarters, and guesthouse have been restored, and the shipyard and the archery field will be restored in the future.
