Sukju

Sukchu, later called Sukch'ŏn, lies on the western approaches to P'yŏngyang. In Koryŏ times it was a defensive centre known as T'ongdŏkchin before receiving the name Sukchu in 983. The Joseon court renamed it Sukch'ŏn in 1416 and raised its administrative rank. Beacon stations in the district relayed warnings along the west coast toward P'yŏngyang.
