Florence Cathedral (Santa Maria del Fiore)

Brunelleschi built the largest masonry dome ever constructed without using formwork – the wooden supporting structure that every other dome builder in history had relied on. The key was a double-shell herringbone brick technique he developed over years and largely refused to document or explain to competitors, making him arguably the most strategically secretive architect in history. The dome was completed in 1436 and sits atop the Florence Cathedral, visible from most of the city’s elevated streets. The building itself is clad in green, white, and pink Tuscan marble in a geometric pattern, original construction beginning in 1296.

Entry to the cathedral nave is free. The dome climb (463 steps, no lift) requires the Duomo Pass at 30 euros, which also covers the Campanile, Baptistery, Crypt, and Opera del Duomo Museum. Book online; timed entry slots for the dome fill by mid-morning on busy days.

What to See

The dome climb is single-file, the passage narrows near the top, and anyone prone to claustrophobia should consider the Campanile instead. The Campanile di Giotto (414 steps) gives better external views of the dome itself – if photography matters more than standing inside the dome, the bell tower is the more useful climb.

The Baptistery of San Giovanni, a Romanesque octagonal building dating from at least the 11th century, has the famous gilded bronze east doors by Lorenzo Ghiberti, which Michelangelo reportedly called the “Gates of Paradise.” The doors currently on the building are reproductions. The originals are in the Opera del Duomo Museum 200 metres away, where they can be seen at close range without crowds. The museum also has Michelangelo’s unfinished Bandini Pieta and Donatello’s late wooden Magdalene – more affecting than most visitors expect.

Eating

The streets immediately around the Duomo are heavily tourist-oriented and overpriced. Walk five minutes toward the San Lorenzo market area or across to the Oltrarno district for better value.

Trattoria Mario on Via Rosina, near the San Lorenzo market, has been serving fixed lunches at communal tables since 1953; expect 12 to 18 euros for a full meal including house wine. No reservations; often a queue by 12:30. This is the correct Florence lunch for value and atmosphere combined.

For coffee, Caffe Gilli on Piazza della Repubblica is the most storied option, a 19th-century cafe with original fittings. A cornetto and cappuccino at the bar runs about 3 euros; sitting down roughly triples the price.

Getting There

Florence Santa Maria Novella station is 10 minutes’ walk from the Duomo. From Rome by high-speed Frecciarossa: 90 minutes, 30 to 80 euros depending on booking time. From Milan: about 100 minutes. Florence has no metro; the city centre is navigable on foot.

Practical Notes

The cathedral dress code (covered shoulders and knees) is enforced at the entrance. July and August peak months; mornings before 10am and late afternoons after 4pm are significantly less crowded than midday. The piazza itself is a meeting point for tour groups, street vendors, and cyclists ignoring pedestrian zones. The cathedral interior is considerably calmer.
