It is the oldest church in existence in Japan and the earliest Gothic wooden church in Japan. It is said to have been built by two French priests, Forno and Ferre, to help the 26 saints who preached in the Xiqiao hills, so it faces the Xiqiao hills. The interior of the church is set with French stained glass produced about 100 years ago. Although most of them were unfortunately severely damaged in the atomic bomb explosion, there are also some restored stained glass mixed with it. The sun shines through the glass into the church, not only illuminating the church. The space for prayer has also been expanded. The church is now listed as a national treasure.
