Gyeryong

Gyeryong City (Korean: 계룡시; RR: Gyeryong-si; Korean pronunciation: [kje̞.ɾjo̞ŋ]) is a city in southeastern South Chungcheong Province, South Korea. The incumbent mayor is Lee Eung-woo. The city was created in 2003 after being split from Nonsan.

Gyeryongdae, a large military complex that serves as the headquarters of the Republic of Korea Armed Forces, is located on Gyeryong's outskirts. Due to the city's proximity to Gyeryongdae, approximately half of its inhabitants are connected to the military as service personnel and their dependents or civilian employees. The city also hosts major South Korean and international military conferences. From 1989 to 1993, the military headquarters were relocated from several locations in Seoul to a more spacious and newly-built integrated complex. The Army and Air Force headquarters were first moved to Gyeryongdae in 1989, followed by the Navy headquarters four years later.

The nearby Mount Gyeryong is considered to have the most qi (spiritual energy) of any mountain in the country and is the heart of Gyeryongsan National Park. As of September 2024, the city's population was 46,687.
