Dongnamgangnu (Southeastern Pavilion)

Gangnu is a pavilion-like structure located on a relatively high place of the fortress walls where troops were able to rest and keep watch on the surrounding areas. During extraordinary situations, it also served as a command post. Among the four such pavilions, Dongnamgangnu has the widest angle view in and out of the fortress. Located opposite the Namgongsimdon (Southern Watchtower), it was built to defend the sections near the Namsumun (Southern Floodgate).
