During the Gihae Persecution of 1839, three French Catholic priests were sentenced to death for spreading Catholicism in Korea. Saint Laurent Joseph Marius Imbert (Bishop), Saint Pierre Philibert Maubant (Priest), and Saint Jacques Honore Chastan (Priest) were beheaded on September 21, 1839 at Saenamteo, currently known as the Saenamteo Catholic Holy Place of the Martyrs, and their bodies were buried at Samseongsan Mountain and later transferred to the grotto of Myeondong Cathedral.
