Jinjuseong Fortress(area 1,760m, stone castle) is a sacred ground that integrates the history and culture of Jinju. It Originally it had been a mud castle, it was rebuilt with stones against frequent invasion of sea marauders in the 5th year of King Woo of Goryeo Dynasty (1379). During the Japanese invasion of Korea in 1592, the General Gim, Si-min had a victory at this castle, which was one of three great victories in the war. In the next year(1593), in the second Jinjuseong Battle, about 70,000 militia corps and government troops resisted to the last meeting a glorious death for their country.

Chokseongmun was completed in 1972, and fortress repair was finished in 1975. The second Restoration Project was started in 1979. Removal of 751 private houses was completed in 1984.
