Milan Cathedral

Milan Cathedral is a huge white church in Milan, Italy. It is covered with pointy spires and thousands of stone statues. It took hundreds of years to finish!

Milan Cathedral, called the Duomo, is a giant Gothic cathedral made of pink-and-white marble. Building began in 1386, and the last details of its front were finished only in 1965. It has more statues than any other building in the world, over 3,000 of them.

Begun in 1386 and run since 1387 by the Veneranda Fabbrica del Duomo, Milan Cathedral took nearly six centuries to complete. Built of Candoglia marble rather than Lombard brick, it brought Gothic builders from across Europe to Milan; Britannica counts 3,159 statues, more than any other building.

Discover Milan Cathedral

Milan Cathedral is in Milan, a big city in Italy.

It is a church made of white marble that looks a little pink. Its roof is covered with tall, pointy spires. On top of the tallest spire stands a shiny golden statue.

Milan Cathedral, which people in Milan call the Duomo, stands in the middle of the city, on a big square called Piazza del Duomo. Britannica says the spot is so central that all of Milan's main streets spread out from it.

It is a Gothic cathedral, a style with pointed arches, tall windows and spires. Its walls are covered in pale marble streaked with pink. Inside there is room for 40,000 people, and Britannica counts it among the world's largest Roman Catholic cathedrals. It also holds a record: more statues than any other building, 3,159 in all.

Britannica describes the cathedral as begun in 1386 and completed over five centuries, with the final details of its facade finished in 1965, on an ancient Roman site so central that the city's main streets radiate from it. Its area of about 11,706 square meters (126,000 square feet) makes it one of the largest Roman Catholic cathedrals, and its interior can hold 40,000 people.

The Veneranda Fabbrica del Duomo, the body founded in 1387 to build and care for it, notes that it rose on the site of the ancient basilicas of Santa Maria Maggiore and Santa Tecla, whose remains are visible in its archaeological area, and calls it the most European of Gothic cathedrals, because of the workers it drew from across the continent. Britannica counts 3,159 statues, 2,245 of them on the exterior, more than on any other building in the world.

Almost six hundred years of building

Workers started building the cathedral more than 600 years ago.

It was so big and so fancy that it took a very long time. Many different builders worked on it, one after another. The last part of the front was finished in 1965!

Building began in 1386. In 1387 Gian Galeazzo Visconti, the ruler of Milan, set up a group called the Veneranda Fabbrica del Duomo to design and build the cathedral. It still looks after it today.

Work went slowly because there was often not enough money or agreement about the design. Builders started at the back, at the rounded end called the apse. The great spire on top was finished in the 1700s, and its golden statue was placed there in 1774. Napoleon pushed for the front to be completed between 1807 and 1813, and the bronze doors went in between 1909 and 1965.

The Fabbrica's history says work probably began in 1386; Britannica records that Archbishop Antonio da Saluzzo commissioned a Gothic plan with a cruciform nave and transept that year. In October 1387 Gian Galeazzo Visconti, Lord of Milan, founded the Veneranda Fabbrica to continue the design and construction; a long succession of architects and engineers means no single author of the design can be named.

Building began at the apse and moved to the transept and first bays of the nave. At the end of the 15th century leading architects and artists, including Leonardo da Vinci, tried to design the tiburium, the structure over the crossing. Design of the facade began in the late 16th century, but a definitive plan came only in the late 18th. The great spire over the crossing was completed in the 17th and 18th centuries and the Madonnina statue set on it in 1774; on Napoleon's initiative the facade was pushed ahead in 1807 to 1813; most roof spires were placed in the 19th century; and the doors were added between 1909 and 1965. Britannica blames the slow progress on a lack of funds and ideas.

Through the years

A cathedral of marble

The first plan was to build with bricks. But the ruler of Milan chose marble instead.

The marble came from a hill far away. Boats carried the heavy blocks along rivers, a lake and canals, right into the city!

At first the cathedral was going to be built of brick, like other churches in the region. But Gian Galeazzo Visconti chose marble from a quarry at Candoglia, in the region of Piedmont, and gave the quarry to the builders in 1387.

The marble blocks traveled by water: down the Toce River to Lake Maggiore, along the Ticino River and the Naviglio Grande canal, and into Milan through locks to a small lake near the building site. Boats carried marble this way until 1920. Because Gothic building was new to Milan, engineers, architects, sculptors and stone-cutters came from all over Europe to help.

Gian Galeazzo Visconti's decision to replace the planned Lombard brick with marble came with a change of style to Gothic, which, the Fabbrica explains, forced it to recruit engineers, architects, sculptors and stone-cutters from across Europe; Britannica notes that the building helped bring High Gothic from beyond the Alps into mainland Italy. On October 24, 1387, Visconti ceded the Candoglia quarry, near Mergozzo in Piedmont, to the Fabbrica and granted free transport of the marble by water.

Blocks went from the Toce River to Lake Maggiore, along the Ticino and the Naviglio Grande canal to the Sant'Eustorgio docks, and through Fabbrica-built locks to a laghetto, a small lake a few hundred meters from the site, now via Laghetto. Water transport lasted until 1920. The marble, white streaked with rose and highly durable, is hard to quarry because its vein is narrow. Britannica notes that the nave is built of brick encased in marble.

Spires, statues and the Madonnina

The roof has so many spires that it looks like a forest of stone!

Stone statues stand all over the walls. Inside, giant stone pillars hold up the roof. Visitors can even walk on the roof and look over the city.

Milan Cathedral is famous for its roof, which bristles with spires, gargoyles and marble statues. Visitors can go up and walk among them for great views of the city. On the tallest spire stands a golden statue called the Madonnina, the "little Madonna," covered in 3,900 pieces of gold leaf.

The building mixes styles from different centuries. The rounded back end is French Gothic, with pinnacles, flying buttresses and lacy stone window frames. Over the center is an eight-sided Renaissance dome with an 18th-century spire. Inside, five long aisles run toward the altar between enormous stone pillars.

Britannica reads the building as a visual contradiction: an eastern apse French Gothic in flavor, with pinnacles, flying buttresses and intricate tracery; an octagonal Renaissance cupola; an 18th-century spire; and a facade it calls Neoclassical, with bronze doors installed in the 20th century. The roof bursts with spires, gargoyles and marble statues and is open to visitors.

Inside, five great aisles run from the entrance to the altar between enormous pillars. The cathedral's best-known statue, the Madonnina, stands on the tallest spire, covered in 3,900 pieces of gold leaf. The Fabbrica still runs its own marble yard, where milling and finishing workers, ornamental marble workers and sculptors use both modern machine tools and hand finishing to make replacement stones and statues.

The Duomo today

Today, the cathedral is still being cared for.

Sculptors carve new statues to replace old, worn ones. Lots of visitors come to the big square in front of it.

People from all over the world visit Milan Cathedral. The Veneranda Fabbrica, the same group founded in 1387, still looks after it. Its workers carve new marble pieces in a workshop, using both modern machines and hand tools.

The Fabbrica also still runs the Candoglia quarry. Restoring the cathedral never really stops: in 2016 a big project began to restore the dome and the structure that holds it up.

The Veneranda Fabbrica, more than six centuries after its founding, maintains the Candoglia quarry with specialist staff and modern technology, and its marble yard in the Certosa area produces ashlars, ornaments and statues; the sculptor, it says, remains irreplaceable for the finishing.

Restoration has been continuous: the great spire was restored in 1840 and again in the 1960s and 1970s, the tiburium pillars underwent a complex structural restoration, the apse and facade were restored late in the 20th century, and in 2016 the restoration of the tiburium and dome began.
