Christianity, which arrived from Rome and the East, first came to the Picenum in the 3rd century, but the invasion of the Lombards in 573 brought about great political, social and religious changes. There then followed a long period that saw shifts in the territorial boundaries of the various dioceses and divisions of church jurisdiction in the area. Today the Province of Macerata is shared between the diocese of Macerata – Tolentino – Recanati – Cingoli – Treia, the archdiocese of Camerino – San Severino Marche, the diocese of Fabriano – Matelica, and the archdiocese of Fermo. Each of these is the result of centuries of history and transformation of which Macerata and Camerino cathedrals are living witnesses, as are the Co-cathedrals of Tolentino, Recanati, Cingoli, Treia, San Severino Marche and Matelica. These are churches which have always been and still now represent for their communities the hub of religious life which is inextricably linked to local history, society, politics and artistic endeavour. Fondazione Carima has decided to devote a special section of its TUMA tourism promotion web portal to these treasure chests of unique beauty, that Benedict XVI called “manifestations of God” as, through their architecture and works of art, they manage to present the mysteries of faith and to announce Christ in visual form.
