Milan Cathedral

23 fascinating facts about Milan Cathedral

1. Location: Milan Cathedral stands in the very heart of the city, on the spacious Piazza del Duomo, Milan’s central gathering place and vibrant hub. Surrounded by elegant palaces, lively cafés, and the magnificent Galleria Vittorio Emanuele II, it forms the spectacular centerpiece of the city’s historic core.
2. Significance: Milan Cathedral is not only the city’s most important landmark but also its spiritual heart. Around 5 million visitors come here every year. With room for about 40,000 people, it is the largest church in Italy, since St. Peter’s Basilica in Rome officially belongs to the Vatican City. By floor area and interior volume, it ranks among the three largest churches in the world, alongside St. Peter’s Basilica and the Cathedral of Seville.
3. Early Christian origin: Long before the present cathedral was built, this site was home to an entire late-antique church complex with two cathedrals and two baptisteries. Santa Maria Maggiore served as the “winter church,” with thick walls and small windows used during the colder months. Santa Tecla was the “summer church,” larger, brighter, and better ventilated, ideal for the warm season. This dual-church system was common in early Christian northern Italy.
4. The baptismal center of early Christianity: Between the two ancient cathedrals once stood the Baptistery of San Giovanni alle Fonti, one of the oldest known baptisteries in the world. Baptisms followed the original early Christian rite: believers descended naked into the octagonal basin, were fully submerged, and then clothed in white garments as a symbol of spiritual rebirth. Remnants of the basin and the surrounding walls can still be seen today in the archaeological crypt beneath the cathedral.
5. Construction history: Duke Gian Galeazzo Visconti took inspiration for Milan Cathedral from the great Gothic cathedrals of Europe, particularly those of Amiens, Chartres, and Cologne. In 1386 he commissioned the project, ordered the gradual demolition of the old churches Santa Tecla and Santa Maria Maggiore, and founded the Veneranda Fabbrica del Duomo — a special workshop that still manages the cathedral’s design, construction, and preservation. After nearly 580 years of building, the cathedral was officially declared complete in 1965.
6. Navigli canals: The marble used to build Milan Cathedral came from the quarries of Candoglia, a small village near Lake Maggiore in northern Italy. To transport the heavy blocks to Milan, the existing Navigli canal network was expanded and adapted for marble shipments. Each block was marked with a special symbol identifying it as cathedral property, which exempted it from customs duties. Leonardo da Vinci later improved the canal locks, allowing precise control of the water flow and making transport much more efficient. Remnants of this historic waterway system can still be seen today in southwest Milan, particularly along the Naviglio Grande and the Naviglio Pavese.
7. Napoleon in Milan: In 1805, Napoleon Bonaparte chose Milan Cathedral as the setting for his coronation as King of Italy. For the ceremony, he ordered the unfinished façade to be completed at record speed. During the event, he placed the Iron Crown of the Lombards on his own head and famously declared, “God has given it to me; woe to him who touches it!” Napoleon ruled the Kingdom of Italy until 1814, when his reign came to an end following military defeats and the Austrian occupation of Milan.
8. World War II: During World War II, Milan was heavily bombed, and the cathedral also suffered damage. To protect it, fragile sections of the façade and important artworks were covered with wooden panels and camouflage materials. Despite several direct hits, the structure remained largely intact. After the war, extensive restoration and repair work began, most of which was completed by 1953.
9. Madonnina: Since 1774, a gilded statue of the Virgin Mary, known as the Madonnina, has stood atop the cathedral’s highest spire. Created by Giuseppe Perego, she is considered the city’s guardian and symbol of protection. From a height of 108.5 meters, she gazes gently over Milan with open arms, holding a scepter as her golden robe appears to flutter in the wind. When taller buildings were later constructed, small replicas of the Madonnina were placed on their rooftops to preserve her presence above the skyline.
10. Statues: With around 3,400 statues, Milan Cathedral is the most richly decorated building in the world. Under the direction of the cathedral workshop, countless marble sculptures were created over the centuries by artists from Italy, France, Germany, Flanders, and Switzerland. Depicting saints, angels, animals, and mythical creatures, these figures give the cathedral its distinctive diversity and vibrant sense of life.
11. Curious statues: Among the most unusual sculptures of Milan Cathedral are The New Law by Camillo Pacetti and The Old Law by Luigi Acquisti, both created in 1810. The female figure of The New Law holds a torch and leans on a cross, bearing a striking resemblance to the later Statue of Liberty. Her counterpart carries the stone tablets of Moses. Together, they symbolize the passage from the Old to the New Testament. Both statues stand on the central balcony of the main façade, high above the main portal. They can be seen from Piazza del Duomo, though their intricate details are best viewed through binoculars.
12. Rooftop terraces: The rooftop terraces of Milan Cathedral are among the city’s most breathtaking viewpoints. Surrounded by slender spires, stone gargoyles, and hundreds of marble statues, visitors can walk along narrow pathways and admire the cathedral from an entirely new perspective. The terraces can be reached by stairs or elevator and are now one of Milan’s most beloved photo spots.
13. Relief of the dragon Tarantasio: On the main façade, just to the lower right of the central portal, is a relief depicting the legendary dragon Tarantasio. It shows a shallowly carved, serpent-like creature with an open mouth and faintly outlined wings. According to legend, the monster once lived in the marshes of the former Lake Gerundo, spreading poison among people and animals until it was slain by the knight Uberto Visconti. The powerful Visconti family later adopted the dragon as their coat of arms and ruled Milan from 1277 to 1447, until their dynasty ended with the death of Filippo Maria Visconti.
14. The Holy Nail: High above the main altar of Milan Cathedral hangs a small crystal reliquary containing the Holy Nail, believed to be one of the nails used in the Crucifixion of Christ. Once a year, usually in mid-September, it is ceremoniously lowered during the Rito della Nivola, when the archbishop ascends to the top of the vault on a cloud-shaped platform. This centuries-old ritual, first recorded in the 15th century, remains one of the oldest continuously practiced religious ceremonies in Europe.
15. Crypt of Saint Charles Borromeo: Beneath the high altar lies the magnificent crypt of Saint Charles Borromeo, where the revered archbishop rests in a glass sarcophagus made of rock crystal and silver. Born in 1538 near Lake Maggiore into a noble family, Charles Borromeo reformed church life in Milan during the 16th century. He founded seminaries, renewed liturgical practices, and dedicated his life to helping the poor and the sick. During a devastating plague, he refused to flee the city and personally cared for the afflicted, earning his place as one of the most beloved figures in Milan’s history.
16. Tombs of other archbishops: Milan Cathedral holds more than twenty tombs of former archbishops, representing over a thousand years of ecclesiastical history. Among the most notable is the tomb of Aribert of Milan from the 11th century, a powerful churchman and political leader of his time. Equally remarkable is the resting place of Federico Borromeo, founder of the Biblioteca Ambrosiana and one of the great patrons of Renaissance art. A more recent monument honors Andrea Carlo Ferrari, who, in the early 20th century, devoted himself to social reform and compassionate care for the poor.
17. Sundial inside the cathedral: In the left aisle of Milan Cathedral lies an exceptionally precise sundial dating back to 1768. At noon, a narrow beam of sunlight passes through a tiny hole in the façade and strikes a bronze line set into the floor, perfectly aligned with true north and marked with zodiac signs and calendar points. When the light touches a specific point, it indicates the exact time of solar noon as well as the sun’s position in the zodiac — revealing both the current sign and the season.
18. Statue of Saint Bartholomew: In the right transept stands the renowned statue of Saint Bartholomew, sculpted by Marco d’Agrate in 1562. Carved from Candoglia marble, it portrays the apostle completely flayed, his muscles and tendons modeled with extraordinary precision, while he drapes his own skin over his shoulders like a cloak. This haunting image reflects his legend: Bartholomew preached Christianity in Armenia and was martyred by being skinned alive.
19. Trivulzio Candelabrum: Also in the right transept stands the monumental Trivulzio Candelabrum — a seven-branched bronze candlestick nearly five meters tall, dating from the 12th century. Its surface is covered with intricate reliefs depicting biblical scenes, plants, animals, and mythical creatures that represent the eternal struggle between good and evil. Originally, real candles burned on its arms, their flickering light bringing the detailed figures to life. Today, the candelabrum is regarded as one of Italy’s finest Romanesque bronze masterpieces and a hidden gem of Milan Cathedral.
20. Stained glass windows: The 55 monumental stained glass windows of Milan Cathedral are among the largest and most spectacular in Europe. Created between the 14th and 20th centuries, they illustrate vivid biblical scenes from both the Old and New Testaments. Particularly stunning is the Apocalypse Window in the central apse — the semicircular space behind the high altar — which, in radiant color, portrays the battle between good and evil, between angels and demons, culminating in the triumph of light over darkness.
21. Organ: The organ of Milan Cathedral is the largest in Italy and one of the most magnificent in the world. It consists of two grand instruments facing each other on either side of the high altar, together housing around 15,800 pipes. Both organs are electrically linked and can be played from a single console. Their richly carved 16th-century wooden cases are themselves works of art, admired as masterpieces of craftsmanship and design.
22. Museo del Duomo: Housed in the nearby Palazzo Reale, the Museo del Duomo tells the story of Milan Cathedral across more than 2,000 square meters of exhibition space. Its 26 galleries display original sculptures, stained glass windows, liturgical treasures, and the large wooden model that evolved over centuries of planning and construction. Many of these artworks were moved here to ensure their preservation. The museum also includes the Church of San Gottardo in Corte, once the private chapel of the powerful Visconti family.
23. Foundation legend: According to an old legend, Gian Galeazzo Visconti, the patron behind Milan Cathedral, was visited by the devil in 1386. With blazing eyes and a threatening voice, the devil demanded that Visconti build a church in his honor, filled with demonic faces and monstrous figures. Terrified, Visconti began the project but dedicated the cathedral to the Virgin Mary instead. The eerie gargoyles and grotesque sculptures that adorn the façade are said to be haunting reminders of this dark tale.
