Florence Cathedral — Brunelleschi’s Dome
A red octagonal dome rises above Florence on two nested masonry shells.

The story behind the place
Brunelleschi’s dome crowns Santa Maria del Fiore. Its inner and outer shells are connected by ribs, while the brickwork uses a herringbone arrangement. The construction also depended on specially designed machinery for lifting heavy materials. The achievement is both architectural and practical: a huge masonry roof assembled through carefully organised work high above the cathedral.
