Jangyeon

Changyŏn occupies the western end of Hwanghae, where a broken coastline opens into the Yellow Sea. Its shores include landing places such as Monggŭmp'o and Pisŏkp'o, sheltered among the headlands and islands. From 1768 the local magistrate also served as a naval commander, directing the maritime forces of five coastal counties and districts. The post reflected the importance of guarding the province's seaward approaches.
