Gangguan Joseon Gunseon (Geobukseon) is a visitor site in Tongyeong where three turtle ships and one panokseon have been rebuilt and placed on the water. It sits at Gangguan, in front of Tongyeong Jungang Market. Visitors can go inside the full-scale vessels and look around the decks. The four ships display similar contents, and there is not much else to see.
