Located in the north-western part of Kyushu island, this serial property consists of ten villages, remains of the Hara Castle and a cathedral, dating from the 17th to the 19th centuries. They reflect the era of prohibition of the Christian faith, as well as the revitalization of Christian communities after the official lifting of prohibition in 1873. These sites bear unique testimony to a cultural tradition nurtured by hidden Christians in the Nagasaki region who secretly transmitted their faith during the period of prohibition from the 17th to the 19th century.
