Tosan

T'osan lies among the hills along the Imjin River, on the eastern side of Hwanghae. The district bore its name from the Silla period and came under Kaesŏng during Koryŏ rule; a magistrate was appointed in 1214. In 1413 the Joseon court assigned it to Hwanghae. Cliffs and rock formations along the river drew the scholar Yi I and his contemporary Paek In'gŏl to admire the scenery.
