For over four decades since it was first developed to provide industrial water, the 1.2㎢ lake area has been isolated with high barbed wire fences set up for water quality control and safety reasons. As time went by, the area has fallen behind in comparison with other regions and gradually became a deserted area. But now, after the wired fence has been removed, various facilities and walking paths were created to compliment the breathtaking scenery and the surroundings.

Saeyeongyo Bridge is the longest pedestrian overpass created in the southern-most area of the country. The bridge, inspired by ‘Tewu’ (Jeju's traditional log boat), was opened in September 2009, and connects Seogwipo Port and Birds Island. The overpass is the first single cable-stayed bridge ever created in Korea. The bridge has a major tower inspired by the wind and a sail and flamboyant LED lights. With the creation of the bridge, it has become much easier for people to travel to Birds Island, which features the island's ecosystem designated as a warm temperate forest conservation zone. The island also has diverse convenience and leisure facilities such as a 1.2km walking path, a public square, wooden deck road, pebble road, forest walking path and theme photo zone.

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.

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.

Until the construction of this bridge, the only way to get to and from Yeongjongdo Island had been by boat. The 4.4 kilometer-long Yeongjong Bridge is the world’s first 3-dimensional self-anchored suspension bridge. The bridge carries both highways and rail lines on its decks, and 10,000-ton ships can pass under the bridge. The bridge was designed to withstand strong winds and earthquake.It is the first bridge in Korea to have been completed through private capital inducement project. In addition to its function as a bridge, it is also an architectural beauty as the shape of the cable and the girder was designed to symbolize the eaves of the traditional Korean tile-roofed house. In 2002, Yeongjongdaegyo Bridge won the Tanaka Award by the Japan Society of Civil Engineers for the first time in Korea.
