Cupola del Brunelleschi
Brunelleschi's dome, completed in 1436, was an engineering breakthrough that solved the problem of spanning the cathedral's enormous octagonal crossing without traditional wooden centering, using an innovative double-shell herringbone brick structure. It remains the largest masonry dome ever built and defined Florence's skyline for centuries.
Climbing the 463 steps takes visitors between the dome's inner and outer shells, past close-up views of Vasari's Last Judgment fresco painted on the interior surface, before emerging onto a narrow exterior gallery with a panoramic view over Florence.
Because the climb is narrow, one-way, and physically demanding, tickets are timed and limited; this is one of the few sights in Florence where advance booking is essentially mandatory rather than optional.
