Once you exit the Doge’s Palace, a few steps away you will find yourself in front of the imposing Duomo. In the years 1474-1488, the Romanesque-Gothic Cathedral was rebuilt from the foundations, based on a design by the Sienese Francesco di Giorgio Martini (1439-1501), according to simple and elegant Renaissance modules, but completed only between 1604 and 1607, with the octagonal dome designed by Muzio Oddi from Urbino (1539-1639) expecting Martin’s project.
The Cathedral has a three-nave plan with a sober neoclassical decoration of pilasters and capitals, marked by the altars of the side aisles that preserve paintings of great historical and artistic value, such as the Martyrdom of St. Sebastian (1535-1612) and the St. Cecilia by Federico Barocci, after Raphael.
Attached to the Dumo is the Albani Diocesan Museum, so named in memory of the patronage of the noble family of Pope Clement XI Albani (1700-1721) who contributed to increasing the “treasure of the cathedral”. This museum houses the most varied ecclesiastical furnishings, from the thirteenth century to the present day: thirteenth-fifteenth-century illuminated manuscripts, chalices and reliquaries, liturgical vestments woven with precious metals.
In the exhibition, divided into three rooms, there are also numerous detached frescoes that tell the spread of the International Gothic. There are also works by great schools such as that of Giovanni Santi, Mannerism and great artists such as Federico Barocci and Federico Zuccari. Finally, the Oratory of the Grotto, an integral part of the Albani Diocesan Museum, which houses part of the collection.
