Duomo di Milano

About Duomo di Milano

📜 History

The construction of Milan Cathedral began in 1386 by order of Archbishop Antonio da Saluzzo, during the political rise of Gian Galeazzo Visconti, who donated in perpetuity the Candoglia marble necessary for the work. The project brought together engineers and architects from across Europe for generations: in 1387, Simone da Orsenigo assumed the role of first chief engineer, and in 1399, the Frenchman Jean Mignot arrived with technical observations on the structure. In 1488, a competition was held to design the central dome, in which Leonardo da Vinci and Donato Bramante participated; the octagonal dome was completed between 1500 and 1510 under the patronage of Ludovico Sforza. In 1577, Cardinal Carlo Borromeo consecrated the building as a church. In 1805, Napoleon Bonaparte ordered the completion of the facade and was crowned King of Italy inside. World War II caused damage from bombing that was promptly repaired. The construction process spanned nearly six centuries, formally concluding in 1965.

🏛️ Architecture

The Duomo di Milano is an example of Italian Gothic with Renaissance elements, built from Candoglia marble whose pinkish hue characterizes its facades and its 135 spires. It measures 158.6 meters in length and 92 meters in width; the central nave reaches a height of approximately 45 meters and the main spire reaches 108.5 meters. The floor plan is organized into five wide naves separated by 40 pillars, with flying buttresses supporting the pinnacles of the roof. The interior capacity is 40,000 people. The first chief engineer, Simone da Orsenigo, began work in 1387; Nicolas de Bonaventure arrived in 1389 and Jean Mignot in 1399. In the Renaissance period, Giovanni Antonio Amadeo, Leonardo da Vinci, and Donato Bramante competed in 1488 for the design of the central dome, of octagonal plan, completed between 1500 and 1510. The facade was finished by Carlo Pellicani under the Napoleonic decree of 1805. The roof is accessible to the public and allows close observation of the sculptural ensemble of the spires. The interior houses the largest pipe organ in Italy, an instrument with five manuals and 225 stops.

⭐ Key Facts

The cathedral is the largest church in the Italian Republic and follows the Ambrosian rite, a liturgy proper to the diocese of Milan with roots prior to the 4th century. It is dedicated to the Nativity of the Virgin Mary (Santa Maria Nascente) and serves as the metropolitan seat of the Archdiocese of Milan. Among its most venerated relics is a nail from the Crucifixion preserved in the lantern of the dome; each year, in the ceremony called the Rite of the Nivola, the nail is lowered for the devotion of the faithful. The interior safeguards works of recognized artistic importance, including the sculpture of Saint Bartholomew Flayed (1562) by Marco d'Agrate, in which the saint carries his own skin as a cloak. The Trivulzio Candelabrum, crafted between the 12th and 16th centuries, also stands out. In 1786, a meridian line for astronomical purposes was installed, designed by Giovanni Angelo Cesaris and Francesco Reggio. In 1805, Napoleon Bonaparte was crowned King of Italy inside, an event that marked the modern political history of the temple. In 2012, a preservation campaign known as 'adopt a spire' was launched to fund the maintenance of the marble structures.

The Duomo di Milano remains open as an active place of worship and as a visiting destination in the historic center of the city. Access to the roof terrace allows visitors to explore a sculptural ensemble spanning centuries of marble craftsmanship. The interior, with its stained glass windows, the meridian line, and the largest organ in Italy, offers a tour that combines religious history, late medieval architecture, and Renaissance art. The cathedral is located in Piazza del Duomo, a landmark of central Milan.
