Jinjuseong (Korean: 진주성; Hanja: 晋州城), was a walled city now in Jinju, South Korea. It was designated Historic Site of South Korea No. 118 on 21 January 1963.
Located on the Nam River and close to the port of Busan, Jinju has long been a key city for invasions from Japan. Originally the walls were built with mud, but they were rebuilt with stones in 1377, and collapsed two years later due to Japanese sea pirates, and thus in the 5th year of King Woo of the Goryeo Dynasty (1379). with the walls being completed in 1380.
