Yeosu was once the headquarter of Cholla Left Navy Division Headquarter in Joseon Dynasty with as many as 3 shipyards where ship and army ship were dried.
Admiarl Lee, Soon-Shin built Turtle Ship with Nah, Tae-Yong, an army officer with excellent ship-building skill during the Japanese invasion in Jeoseon Dynasty. The Turble Ship is thought to have been built for the first time in three places like the shipyard of headquarter in Cholla Left Navy Division Headquarter(currently Jinnamgwan), Bangdapjin shipyward(currently Dolsan) and Suncheonbu Shipyard(currently Sijeon-dong, Yeosu). According to the diary kept by Admiral Lee during the Japanese invasion in Jeoseon Dynasty, the Turtle Ship is recorded as Yeong Turble Ship, Bangdap Tuirtle Ship and Suncheon Turtle Ship.
