The Basilica di Santa Maria del Fiore (Basilica of Saint Mary of the Flower) was begun in 1296 and completed in 1436 with the dome engineered by Filippo Brunelleschi (1377 – 1446); he won the commission in 1419: although the building had been designed a century earlier, no one had any idea about how such a dome was to be built. He succeeded brilliantly. The Campanile, the 84 metres high free standing bell tower was designed by Giotto di Bondone and built from 1334 to 1359.
