Seosan

Sŏsan lies on the western side of Ch'ungch'ŏng, where the coast is broken by bays and peninsulas. Nearby Haemi's stone-walled town served as a military headquarters under Joseon. Its garrison was already important in the fifteenth century, and an inscription on the south gate records work in 1491. In 1712 another military command was moved to Haemi, where the county magistrate also held the post of commander.
