The northern part of Yanggu County was part of the front line for much of the Korean War, and now borders the Demilitarized Zone. Several Korean War battle sites are located in Yanggu County, including Bloody Ridge, Heartbreak Ridge, and Hill 1179 (Daeusan).
Yanggu is located in what is claimed to be the geographic center of the Korean peninsula. Dochon-ri village in Nam-myeon[2] in Yanggu is called the "navel of Korea".[3]
