Urbania Cathedral

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.

Cagli Cathedral was begun in 1292 and completed in the 14th century. The building was completely restructured from 1646 and consecrated on October 10, 1677. The work was completed in 1754 with the works carried out in the chapel of the Santissimo Sacramento. The violent earthquake of 3 June 1781 caused the collapse of the dome and a large part of the building. A vast reconstruction was necessary and the new cathedral, deprived of the dome, was reopened to the public in 1792. In 1997, a new earthquake required further interventions and the cathedral was finally returned to the public in 2004.

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.
