Gyeryong (; pronounced as /ko/) 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, 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.[1]
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.
Gyeryong city is one of the newest cities except for new cities near Seoul. The establishment as a city was made in 2003, when it broke from Nonsan.
According to data, Gyeryong city and surrounding area were called "Yeonsan-Gun" in 1896. After Japanese colonization, it was incorporated to Nonsan. Later Gyeryong was chosen as the site for military. In 1989, Military and army headquarters, Gyeryongdae, moved to Gyeryong City. In 1991, it was designated as special area by president. The congress voted and decided via a special legislative bill that Gyeryong city be establishedon June 30, 2003. Six months later, the city officially came out.[2]
The area currently called Gyeryong city was known to be Shindoan among the older residents. Gyeryong is also known to be a satellite city of Daejeon due to its geographical closeness.
Pelicana Chicken has its headquarters in the city.[3]
Due to the proximity of Gyeryongdae, the Republic of Korea Armed Forces and Ministry of National Defense are major employers.
