Florence Cathedral (Duomo)
The Cathedral of Santa Maria del Fiore, crowned by Brunelleschi's revolutionary dome, is Florence's most iconic landmark. Construction began in 1296 and the dome was completed in 1436. The exterior features stunning white, green, and pink marble. Climb 463 steps to the top of the dome for panoramic city views. Giotto's bell tower and the Baptistery of St. John complete the magnificent ensemble.
