Santa Maria del Fiore, known simply as the Duomo, stands in Piazza del Duomo in Florence, Italy. This basilica is one of the world's largest churches, begun in 1296 under Arnolfo di Cambio. It anchors a complex that also includes Giotto's Campanile and the Baptistery.
Why it is worth the trip
The facade glows in alternating bands of white, green, and pink marble, and it is hard to look away from it. Step inside and let your eyes adjust to the vast, dim space of the three wide naves under pointed Gothic arches. Look up at the cupola, one of the largest masonry domes ever built, which Brunelleschi raised without a temporary wooden frame. Below the floor, the crypt holds the remains of the earlier cathedral, Santa Reparata, and Brunelleschi's tomb.
The best time to go
Go early in the day, when the piazza is quieter and you can take in the facade and the scale of the dome before the crowds build. Visiting outside the busiest holiday periods also makes the climb and the interior more relaxed.
How long to allow
Allow at least half a day to take in the cathedral, the dome climb of 464 steps, and the rest of the piazza. Add more time if you want to visit the Baptistery and the museum properly.
Getting there
The Duomo sits in the heart of Florence's historic center, so it is easy to reach on foot from many other central sights.
What to book ahead
Reserve your entry to the dome or the Museo dell'Opera del Duomo in advance to avoid long waits. Booking ahead also gives you the freedom to enjoy the climb without stress.
Nearby
Within the piazza, you can visit Giotto's Campanile, the Baptistery with its bronze doors, and the Museo dell'Opera del Duomo. A walk from here also reaches the Galleria dell'Accademia.
