The Catholic Ganggyeong Holy Site Church stands in Hwangsan-ri, Ganggyeong-eup, Nonsan, near the Ganggyeong port. Built in 1961, its interior is arranged with pointed arches. The site is known as the place where Father Kim Dae-geon arrived at Hwangsanpo near the Ganggyeong port at 8 p.m. on October 12, 1845. The building's interior and exterior recall a European church.
