Sunju

Sunchu lies on the Taedong River in the inland country northeast of P'yŏngyang. The river and its tributaries pass through a landscape of limestone hills and valleys. Koryŏ established a county here in 939 and renamed it Sunchu in 983, appointing a defence commissioner. An old fortress at Chasan is associated with the generals Kim Ch'wi-ryŏ and Cho Ch'ung, who fought the Khitan in the early thirteenth century.
