Cagli Cathedral

The Cathedral of Urbania dates back to the ancient Benedictine Abbey of San Cristoforo del Ponte in the 9th century. The building was renovated by the commendatory abbot Cardinal Bessarione in the second half of the 15th century. On this occasion the relics of the saint were transferred to the church. The church became the cathedral of the new diocese of Urbania, established on 18th February 1636. In the 18th century the church was again renovated in a neoclassical style according to the plans of the architect Giuseppe Tosi. The façade (1870) and the new bell tower (1958) are late: the old medieval bell tower is still present on the side.

The Cathedral of Urbino was first built in 1021. In the 15th century, on the initiative of Federico da Montefeltro, the cathedral was rebuilt according to a design attributed to the Sienese Francesco di Giorgio Martini, the Duke's official architect, and completed in 1604. The project, simple and bare, consisted simply of three naves supported by white colonnades. The earthquake of 12 January 1789 caused the collapse of the dome and necessitated the reconstruction of the cathedral according to a project by the Roman architect Giuseppe Valadier (1762-1839), who completed the building in 1801.

Fossombrone Co-cathedral was originally a Benedictine abbey, almost entirely rebuilt in neoclassical style by Cosimo Morelli d'Imola in 1776-84, with the exception of the 15th-century bell tower. It is characterised by a façade divided into three parts by high pilasters that extend the central part.
