Chongbang Fortress

Jŏngbang Castle, also known as Chongbang Fortress, is a significant archaeological site from the Koguryo era, located near Sariwŏn in North Hwanghae Province, North Korea. This mountain fortress was originally constructed in the 4th century CE to protect the Koguryo capital, Pyongyang. Its strategic design incorporates over 12 kilometers of stone walls, some reaching heights of 10 meters, cleverly utilizing the natural terrain of Mount Jŏngbang's ridges and cliffs for defense. The fortress features four large gates, with the southern gate being the best preserved, and contains remnants of commander's posts, barracks, arsenals, armories, granaries, and storehouses. The Sŏngbul Temple, founded in 898 CE within the fortress, adds religious significance to the site. The fortress was reconstructed in 1632 by Kim Ja-jeom, highlighting its continued historical importance.
