Cheonjugyo Suyeong Jangdaegol Sunghyo Seongji is a Catholic martyrdom site in a residential area of Gwangan-dong, Busan. Eight people, including Yi Jeong-sik John and Yang Jae-hyeon Martin, were executed here by military beheading on September 19, 1868, during the Byeongin Persecution. The site was reconfirmed as a place of martyrdom in 1977 when Jangdae stone and roof tile fragments were excavated. Inside are a small park commemorating the eight martyrs and a pilgrimage stamp, managed by Gwangan Catholic Church, with no separate parking lot.
