Gyeryong (Korean pronunciation: [kje̞.ɾjo̞ŋ], Korean: 계룡시) is a city in southeastern South Chungcheong province, South Korea. The current mayor is Choi Hong-Mook. The city was created in 2003, by a split from Nonsan city, following prolonged local agitation. Located on the outskirts of the city is a large military complex known as Gyeryongdae (Hangul: 계룡대), which is home to the headquarters of the Republic of Korea Armed Forces branches. Due to the city's proximity to Gyeryongdae, approximately half (47%) of its inhabitants are connected to the military, as service personnel and their dependents or as civilian employees. The city hosts several major Korean and international military conferences. From 1989 to 1993, the headquarters relocated from various locations in Seoul into the more spacious newly-built integrated complex. The Army and Air Force headquarters first moved there in 1989, followed by the Navy headquarters four years later. Gyeryong Mountain (Korean: 계룡산), adjacent to the city, is considered the mountain with the most qi (spiritual energy) in Korea. It is also the heart of Gyeryongsan National Park. As of December 2020, the total population of the city was 42,822. From Wikipedia
