Veneranda Fabbrica del Duomo di Milano

Its main headquarters are located in the eponymous palace in Piazza del Duomo.

Despite the Duomo being a consecrated Roman Catholic church, the Venerable Factory is completely independent of the Holy See.

At the time, the construction of the Duomo had already begun, and was supervised by Superstantia di Santa Maria Maggiore, a similar organization established by archbishop Antonio da Saluzzo, which was then replaced by the Fabbrica.

The Fabbrica was responsible for a major change in the plans for the Duomo, including the adoption of the new Gothic style that was then becoming popular all over Europe (especially France).

Over the centuries, artists and workers from the Fabbrica del Duomo have collaborated with other notable architectural projects in the city; for example, sculptors of the Fabbrica have been involved with the decoration of the facades of Palazzo Marino (Milan's city hall).
