Main gate Osan AB

The base is located 4.7 miles southwest of the town of Osan, for which it is named, and 40 miles south of Seoul, the capital city. Prior to the invasion of the Republic of Korea by the North Korean communists in 1950, the area consisted of several tiny farming villages near the hillsides and a large number of rice paddy areas where the runway now lies. A large ginkgo tree marked the village square of one of these villages and still stands on a hill in the base golf course.
