The dazzling Duomo is Florence’s largest and most important church. Officially dedicated to the Virgin Mary, this architectural landmark - featuring Filippo Brunelleschi’s eye-catching red-tiled cap - is a feat of engineering unmatched in Italy since ancient times. If you're in Florence, seize the chance to bypass the crowds, skip the line and get an English guided tour - plus access to the Secret Terraces!The dome that crowns the Duomo reinvented not only architecture, but language too. The word 'dome' in English comes from this very vaulted roof. If you’re feeling adventurous, a trip to the top of the lantern guarantees an amazing view of Florence looking out, as well as a close-up peek of Giorgio Vasari’s frescoes on the inside. Speaking of the inside, nothing prepares you for Florence’s Duomo when you first walk in. Your tour guide will explain the fascinating history and facts as you mouth the word 'wow' at architecture by the likes of Arnolfo di Cambio, Giotto, and Brunelleschi. You’ll also ogle at awe-inspiring ornamentation, from Paolo Uccello’s to the 600-year old stained glass windows crafted by the likes of Donatello, Ghiberti and Andrea del Castagno. Heading up to the Secret Terraces, over 30 meters from the ground, will put you in a maze of wonder. Walk the corridors, check out the views, and let your guide explain the significance of all that you see. A visit to such lofty heights is not for the faint-hearted, but if you make it up the 463 steps you most definitely deserve a gelato afterwards! How's that for incentive? Many of Brunelleschi’s contemporaries doubted that the one-time goldsmith could pull off his famed dome. Emboldened by his knowledge of mathematics and physics, Brunelleschi knew better. Completed in 1436, his iconic churchtop creation continues to stand strong.
