・It is said that the history of Christianity on Iojima Island started in the Edo Period, when Christians who managed to survive amid the ban on Christianity came to the island from various areas, including Amakusa, by sea.
・After the discovery of Hidden Christians in 1865, the Japanese government removed the bulletin board banning Christianity in 1873, and Magome Church was constructed.
・In 1890, Father Marmand erected a white plaster Gothic church. Later, the church collapsed due to lightning and typhoons. In 1931, the church was reconstructed with a local carpenter serving as the master builder.
