After the nationwide repression of Catholicism in 1791, a group of Catholics came to what is today known as Yeonpung Sanctuary to practice their religion in secret before they were discovered and executed in 1801. Today, Yeonpung Sanctuary is a Catholic sanctuary dedicated to the martyrs. Yeonpung Sanctuary has a Catholic church, a crucifix, and a sculpture and tomb of Hwang Seokdu (Luke; 1813-1866), a saint born in Yeonpung and martyred as a Catholic.
