Florence Cathedral took nearly six centuries to reach its present form. The medieval church was begun in 1296, Brunelleschi’s Dome was raised between 1420 and 1436, and the marble façade was only finished in 1887. This guide explains how the Cathedral, Baptistery, Bell Tower, Santa Reparata and Museum fit together, what to look for inside, and how to plan a visit in 2026.
“Santa Maria del Fiore” means Saint Mary of the Flower, a reference to the lily, Florence’s symbol. Piazza del Duomo holds five linked monuments built over more than a thousand years, plus a museum that protects many of their originals. UNESCO lists them as part of the Historic Centre of Florence.
Begun in 1296 to replace the smaller church of Santa Reparata, the Cathedral was designed by Arnolfo di Cambio and enlarged by Francesco Talenti in the mid-1300s. About 153 metres long, it was one of the largest churches in Europe when it was completed. It is still Florence’s working cathedral.
Filippo Brunelleschi raised the octagonal Dome without the huge wooden frame that normally supported a vault during construction. He used two shells, herringbone brickwork and around four million bricks. It is still the largest masonry dome ever built.
The painter Giotto began the Campanile in 1334. After his death in 1337, Andrea Pisano continued it, and Francesco Talenti completed it in 1359. It rises about 85 metres, with 414 steps to the terrace.
The octagonal Baptistery opposite the Cathedral is the oldest building on the square, consecrated in 1059. Dante and many Medici were baptised here. Its bronze doors by Andrea Pisano and Lorenzo Ghiberti are among the most famous in the world.
Beneath the Cathedral floor lie the remains of the earlier basilica of Santa Reparata. It was built around the 5th century and demolished in the 1370s as the new Cathedral grew around it. Excavations from the mid-1960s uncovered mosaic floors, tombs and, in 1972, Brunelleschi’s grave.
The Museum holds around 750 original works made for the monuments, including Ghiberti’s Gates of Paradise, Michelangelo’s Florentine Pietà and Donatello’s Magdalene. Reopened in 2015 after a major expansion, it covers about 6,000 square metres over three floors.
Arnolfo di Cambio’s original façade was never finished and was dismantled in 1587. For almost 300 years the front stayed bare. The white, green and pink marble façade you see today was designed by Emilio De Fabris, built from 1876 and completed in 1887.
You do not need to memorise every architect. These turning points explain why the complex looks unified even though it was built over many centuries.
By 1418 the Cathedral had an octagonal opening about 45 metres wide and no one knew how to cover it. There was not enough timber in Tuscany to build a conventional wooden frame at that height. Brunelleschi, a goldsmith by training, proposed a dome that would support itself as it rose.
The Dome has a thick inner shell and a lighter outer shell, joined by 24 ribs (eight visible from outside). The visitor staircase climbs between the two shells, so you literally walk through the structure.
Bricks were laid in a herringbone pattern so each ring locked into the last as the walls curved inward. Rings of sandstone and iron act like belts to stop the Dome spreading outward.
Brunelleschi designed the marble lantern that crowns the Dome, but he died in 1446, just as work began. Michelozzo and others finished it. The gilded copper ball was raised in 1471 by Verrocchio’s workshop, where a young Leonardo da Vinci was training.
Vasari and Zuccari painted about 3,600 square metres of the Last Judgement on the inner shell between 1572 and 1579. Climbers pass along a gallery at the base of the Dome with a close view of the frescoes and the Cathedral floor far below.
The visual impact is immediate, but the buildings become far more interesting once you understand what each part was designed to do.
The Cathedral, Bell Tower and Baptistery share geometric panels of coloured marble. The Baptistery’s older white-and-green pattern set the style that the Cathedral and Campanile echoed.
After the richly decorated exterior, the interior feels austere: grey sandstone pillars, wide Gothic arches and plain walls. Florentines valued the space itself, and many decorations were later moved to the Museum for protection.
The lower levels originally carried reliefs and statues of human labours, the planets, virtues, liberal arts, sacraments, prophets and sibyls. Many originals by Andrea Pisano, Luca della Robbia and Donatello are now in the Museum, replaced outside by copies.
The octagonal Baptistery was so admired that Florentines once believed it was a Roman temple. Its mosaic ceiling, marble floor and bronze doors link baptism, civic identity and some of Florence’s greatest artists.
The unfinished front stood bare for nearly three centuries, and several competitions failed. De Fabris’s neo-Gothic design finally matched the medieval sides, with statues of the Virgin, the Apostles and the Florentine art world.
Walk around all three buildings before you queue for a climb. Their alignment, marble patterns and changes in scale explain the complex better than any single view.
Visitors often assume every famous Duomo artwork is still in place. Many originals have been moved to the Museum for conservation, while the Cathedral keeps several remarkable works.
Above the main entrance, Uccello’s 1443 clock uses the old “Italian hours” system. Its single hand runs anticlockwise, and the 24-hour cycle ends at sunset. It still works.
On the left wall, Uccello’s fresco of the mercenary captain John Hawkwood (1436) and Andrea del Castagno’s Niccolò da Tolentino (1456) imitate bronze statues in paint, a cheaper way to honour the city’s commanders.
Domenico di Michelino’s painting of 1465 shows Dante holding his poem, with Florence, the Dome and the mountain of Purgatory behind him. It honours the exiled poet in his home city’s cathedral.
The original gilded East Doors of the Baptistery, restored over nearly three decades, are displayed in the Museum. Their ten Old Testament panels use perspective in a way that shaped Renaissance art.
Carved by Michelangelo in his seventies, around 1547–1555, for his own tomb, then partly broken and abandoned, this Pietà includes a hooded figure of Nicodemus often thought to be a self-portrait.
Donatello’s wooden Mary Magdalene, from the 1450s, shows the saint worn and emaciated after years in the desert. It once stood in the Baptistery.
For conservation, the original reliefs and statues from Giotto’s Bell Tower were moved indoors during the 20th century and replaced outside by copies. They include Donatello’s prophets, among them the bald “Zuccone”.
The Museum displays wooden models linked to the Dome and lantern, along with tools and hoisting equipment from the building site. They help you picture the building work before or after your climb.
The archaeological area proves that Santa Maria del Fiore did not rise on empty ground. The new Cathedral literally grew around an older sacred building, which stayed in use until the 1370s.
Santa Reparata was Florence’s cathedral for centuries. Its remains, reached by a stair from the nave, include layers from the early Christian period to the Middle Ages.
Excavations from 1965 to 1974 exposed the remains beneath the modern floor. In 1972 archaeologists found Brunelleschi’s tomb, a rare honour of burial inside the Cathedral he completed.
Visitors often call it the Duomo crypt, but it is the excavated remains of the earlier basilica. It is included in all three passes, and Ghiberti Pass holders must enter at the start of their chosen time slot.
History at the Duomo is not frozen. Restoration affects what you can see now, so separate the permanent story from temporary 2026 conditions.
Scaffolding covers the 13th-century mosaic ceiling, which cannot be seen on a normal visit. A special guided tour of the restoration site offers a close-up view from the scaffolding.
The tower stays open, but restoration work may partly reduce the views from the top.
Because many originals are now in the Museum, it is essential to understanding the complex, especially while parts of the monuments are covered.
The history is easier to enjoy when the logistics are clear. The Cathedral itself is free. The other monuments need one of the three official passes, and the Dome needs a reserved time slot.
No ticket or booking is needed. The Cathedral is closed to visitors on Sundays and during religious celebrations, and queues can be long at midday.
463 steps with no lift, through narrow passages between the two shells. Book a fixed time slot with the Brunelleschi Pass.
414 steps to a terrace about 85 metres high. It gives the best view of the Dome itself.
For the Cathedral and Baptistery, no flip-flops, bare shoulders or legs uncovered above the knee.
Large bags must be left at the free cloakroom at Piazza del Duomo 38/r (open about 7:30–20:15). Metal detectors check all entrances.
Age limits apply to the Dome and Bell Tower climbs, and they are not suitable for people with heart conditions, vertigo or claustrophobia.
Each pass is named after a Duomo artist. What matters is which monuments it includes. Children aged 7–14 pay a reduced price, and children under 7 go free.
| Pass | Adult | Age 7–14 | Includes | Best for |

An official guided route with priority access to the Dome, about €50 for adults. It is useful when individual Dome slots are sold out.
An official guided visit of the Cathedral interior with an expert, about €17 for adults.
An official guided tour of the Baptistery and Museum, about €25 for adults.
Prices and access conditions can change. Check the official Opera di Santa Maria del Fiore ticket site for your date before booking.
This order tells the story more clearly than jumping randomly between monuments. Allow a full day for the Brunelleschi Pass, or half a day for the Ghiberti Pass.
Start with the oldest monument, its marble patterns and its doors.
See the vast later church, then go down to the building it replaced.
The Campanile shows the 14th-century vision; the Dome, the 15th-century solution.
See them up close, away from the weather and the crowds outside.
Compare the originals with the copies you saw on the tower.
Finish with the models and tools that explain how the Dome was built.
These answers separate the historic monuments from modern ticketing and common travel shorthand.
In everyday use, “Duomo” means the Cathedral of Santa Maria del Fiore, but it often refers to the whole complex on Piazza del Duomo.
“Saint Mary of the Flower”. The flower is the lily, the symbol of Florence.
No. Arnolfo di Cambio designed it in 1296, and Talenti enlarged it. Brunelleschi built the Dome between 1420 and 1436.
No. Giotto began it in 1334 and died in 1337. Andrea Pisano continued it, and Francesco Talenti completed it in 1359.
No. It is a 19th-century neo-Gothic façade by Emilio De Fabris, built between 1876 and 1887.
No. The original bronze doors are preserved in the Opera del Duomo Museum, and replicas hang on the Baptistery.
463 steps, with no lift. Giotto’s Bell Tower has 414 steps.
Yes. The Cathedral is free and needs no ticket. The Dome, Bell Tower, Baptistery, Museum and Santa Reparata need one of the official passes.
In the Pazzi Conspiracy, Giuliano de’ Medici was murdered during Mass. His brother Lorenzo the Magnificent escaped into the sacristy.
Yes. Santa Maria del Fiore is the seat of the Archbishop of Florence, so visiting hours fit around services.
Begin with the Baptistery’s older history. Then see the medieval Cathedral and Bell Tower, understand Brunelleschi’s Dome as the answer to a structural challenge, and use Santa Reparata and the Museum to connect what survives above ground with what Florence preserved below and indoors.
