Ch'ŏnju-sa is a Korean Buddhist temple located on the southern slope of Yaksan mountain, in Yongbyon, North Pyongan province, North Korea. It is listed as National Treasure #46 in that country. Founded 1684 during the mid-Joseon dynasty the temple today retains its main prayer hall, known as Pogwang Hall (普光殿); the Chonju Pavilion (天柱樓), once known as one of the six most scenic spots in Yongbyon; and several lesser outbuildings, including storage rooms, and dormitories. Many buildings still feature delicate original paintings in a well-preserved state.
During Toyotomi Hideyoshi's invasions of Korea in the late 16th century, the temple was used as an outpost for the bands of warrior monks who helped defend the country against the Japanese.
