Florence Cathedral (Duomo di Firenze)
The dome arrives before everything else — you see it from across the city, from hilltops, from train windows — and yet nothing quite prepares you for standing underneath it. Filippo Brunelleschi finished the largest masonry dome ever built in 1436, and it has never been surpassed. The cathedral itself, Santa Maria del Fiore, took nearly a century and a half to complete, its marble skin — green from Prato, white from Carrara, red from Maremma — laid in the 1870s and 1880s in patterns that look almost embroidered from a distance.
Inside, the scale does something strange to sound and light. The fresco covering the dome's interior — the Last Judgment, painted by Giorgio Vasari and Federico Zuccari between 1572 and 1579 — looms overhead in a way that floor-level photographs never capture. Brunelleschi himself is buried in the crypt below, in the remains of the older church of Santa Reparata that the cathedral replaced.
💛 What travellers fall for
People who come back tend to split their visits: the cathedral itself first, free and unhurried, then a separately timed slot for the dome climb — 463 steps through the double-shell structure, with a vertiginous catwalk around the base of the fresco before the view opens at the top. The campanile, Giotto's 85-metre bell tower, gives a different angle on the dome and is often quieter.

The first stone went down on 8 September 1296, with Arnolfo di Cambio as architect. After his death in 1302 work slowed, then stalled. The Arte della Lana, the wool merchants' guild, took over patronage in 1331 and appointed Giotto as master builder in 1334 — he designed the campanile but died in January 1337. Andrea Pisano continued until the Black Death halted everything in 1348. Francesco Talenti resumed in 1349, finished the campanile, and enlarged the whole scheme.
The dome remained unsolved for decades. In 1418 the guild ran a competition; Filippo Brunelleschi, backed by Cosimo de' Medici, beat Lorenzo Ghiberti with a plan to build a double-shell structure without temporary wooden centering. Work began in August 1420 and the cathedral was consecrated by Pope Eugenio IV on 25 March 1436. The marble façade came much later, completed between 1876 and 1887 to a Neo-Gothic design by Emilio De Fabris.
