Jinju National Museum is located within Jinju Castle. After opening in 1984, it reopened in 1998 under the name of “Imjin Waeran Specialty Museum”. The exhibits of the museum are based on Imjin Waeran (Japanese Invasion in 1594), instead of having a purely local flavor. Jinju is the site of the greatest battle of Imjin Waeran, the battle of Jinju Castle, which is why there are many relics about the war at the museum, such as Chokseokru. On the 1st floor you can see literature, paintings and listen to music about the war. You can see the record of POWs and the progress of the war, in the point-of-view of westerners. The exhibited relics were excavated from around the country, and even include relics from Japan, giving you a more complete picture, and the theme based arrangement of the exhibits make it easier to understand the war as a whole. Along the passage you can see many items depicting the major events of the war. There is an exhibit hall called Du-Am Hall with about 179 relics, mainly paintings, pottery, and craftwork, which were donated by Mr. Du-Am. On the 2nd floor you can actively experience the progression of the events in the war. The relics are arranged chronologically, classified by soldier, class, and weapons, etc. The exhibit hall starts with the exhibit on the outbreak of the war, and ends with the book Ichungmugong, which contains the will of General Yi Sun-Sin. You can also see a large-scale model of Geobukseon (Turtle Ship), which was the pride of the Korean Navy at the time.
