Standing tall amid the iconic city skyline is the majestic Florence Cathedral (officially known as the Cathedral of Santa Maria del Fiore) and its red-tiled cupola. A symbol of this glorious city and marked by its Gothic beauty, no trip to Florence is complete without entering its hallowed bronze doors.A hundred and fifty years in the making, it was Arnolfo di Cambio who first started working on it in 1296. Its lofty dome was added much later in 1436 by Filippo Brunelleschi. His revolutionary design, which incorporates a second inner dome and interlocking brickwork to reduce the structure's enormous weight, was celebrated as a feat of engineering. Brunelleschi’s dome remains the largest ever constructed in brick.In the 19th century the cathedral received its now familiar elaborate Gothic facade in pink, white and green polychrome marble. Designed by architect Emilio de Fabris, it replaced the incomplete original, which was torn down in the 16th century. In constrast the cathedral’s interior is surprisingly stark, as most of its art works have been moved to the Museo dell'Opera del Duomo. That said you can still admire impressive frescoes, up to 44 stained-glass windows and the excavated remains of the basilica of Santa Reparata that lie beneath the cathedral.The cathedral complex is completed by the Baptistry of San Giovanni, with its striking golden door (the aptly named Gates of Paradise) and shimmering ceiling mosaic, along with Giotto’s graceful campanile. Climb the latter for sweeping panoramic views from its terrace. You can also admire masterpieces by Michelangelo, Arnolfo, Ghiberti, Donatello, Luca della Robbia, Antonio Pollaiolo, and Verrocchio at the nearby Museo dell’Opera.Opening hours Cathedral 10am-4.30pmDome 8.30am-7.00pmBaptistry 8.15am-10.15am & 11.15am-7.30pmBell Tower 8.15am-7.20pmCrypt 10.00am-5pmMuseum 9.00am-7.00pm
