Seobukgangnu (Northwestern Pavilion)

Gangnu is a pavilion-like structure positioned on a relatively high part of the fortress, where troops were able to rest and keep watch on the surrounding areas. During emergency situations, it also served as a command post. One of four such pavilions at the fortress, Seobukgangnu was built as a command post at a point opposite Mt. Sukji for troops deployed near Hwaseomun.
