What makes this Catholic place significant
Japan’s oldest surviving church is the place where hidden Christians revealed their faith to Fr. Bernard Petitjean in 1865. It is both a minor basilica and the cathedral component of the UNESCO Hidden Christian Sites inscription.
Begin Nagasaki here, where descendants of Japan’s hidden Christians approached the newly built church and quietly disclosed the faith their families had preserved through generations of persecution.
