Hansando Island, located in the middle of Hallyeo Haesang National Park, is an important historical site. This is where General Lee Sun-Shin (1545 ~ 1598) won his great victory using the "Turtle Boat" (an ironclad warship shaped as a tortoise) by commanding the naval forces of Chungcheong, Jeolla and Gyeongsang Provinces at the beginning of Imjinwaeran, the Japanese invasion of Korea (1592-1598).In Hansando Island, a 960 square km large forest is blanketed with camellias and old red pines. In the woods, there is Jeseungdang, which was the strategic headquarters of General Lee Sun-Shin where he commanded the war for five years during the Japanese occupation of Korea in 1592. Jeseungdang has a five-page documentary called Chungmugong that recorded the activities of Lee Sun-Shin which depicts the events of that period. You can also see the barracks, The Suru Watch Tower, and Hansanjeong, where soldiers were trained in archery. The Suru Watch Tower overlooks a fine view of the sea, along with a view of Jeseungdang.The active cultivation of oysters, ascidians, brown seaweed and pearls is attracting more tourists to this area. The coast of Hansando has also become a famous fishing spot.
