Jeongseon

Chŏngsŏn lies in the mountainous upper basin of the South Han River, where several streams meet among steep valleys. Its name and administrative status changed repeatedly under Koryŏ; the name Chŏngsŏn was restored in 1353. During the Joseon period the county briefly came under Wŏnju in 1466, but was re-established the following year. The surrounding high country has long given the district a distinctive landscape.
