National Treasure Oura Cathedral admission ticket (Nagasaki Prefecture)

• National Treasure Oura Cathedral

Officially named the Church of the Twenty-Six Martyrs of Japan, the dedication ceremony was held on February 19, 1865. Built at a time when Christianity was still banned in Japan, the church is where Christians who had been hiding for approximately 250 years confessed their faith on March 17, 1865. In 1933, it was designated a National Treasure under the National Treasure Preservation Act. In 1953, it was designated a National Treasure under the Cultural Properties Protection Act as Japan's first Western-style wooden building. The Latin Seminary (a national important cultural property), built in 1875, and the former Archbishop's Palace (a prefectural important cultural property), built in 1915, were both opened as Christian museums on April 1, 2018. In the same year, the "Hidden Christian Sites of Nagasaki and the Amakusa Region" were registered as a World Heritage Site.
