A three-floor ‘Geobukseon’ (Turtle Ship) that was recently restored using historical research is seen at a shipyard in Seocheon, South Chungcheong Province, South Korea, yesterday. This type of warship was originally designed by Korean naval commander Yi Sun-shin and was used to fight off invading Japanese forces in the early 15th century. The ship is 25.6m long, 8.67m wide and 6.06m high
