The Samdo Sugun Tongjeyeong in Tongyeong's Munhwa-dong is the site of a Joseon-era naval headquarters. Its grounds hold the national treasure Sebyeonggwan, old trees, and stone paths, and look down over Tongyeong Port. From 1593 to 1895 it commanded the three provinces' naval forces for 303 years. During the National Heritage Media Art period, ten works are shown from 19:00 to 21:30.
