Yeongwon
Yŏngwŏn lies in the mountain country of the upper Taedong River. It became a separate county in 1466, when it was detached from Yŏngnyŏng under the direction of the frontier commissioner Han Myŏnghoe. Northern security remained a concern in the seventeenth century: a military settlement was established in 1633, and the Yŏngsŏng garrison followed in 1684. Hills and river valleys frame this inland frontier district.
