What we do

The unique beauty and majesty of the Duomo have always fascinated and inspired wayfarers, singers, poets and citizens from all over the world.

The Duomo is the largest Cathedral in Italy, with over 6 million visitors each year, and it owes its unique appeal to the precious, but delicate Candoglia marble, covering its whole surface.

The fragility of this marble makes a great deal of maintenance work essential; each year the Veneranda Fabbrica has to arrange for and pay for the work to guarantee the safety of the visitors and the beauty of this timeless work of art.
