The 4th largest cathedral in the world is located in Florence Italy. Florence’s cathedral is the fourth largest in the world after Saint Peter’s (Rome), Saint Paul’s (London), and the Duomo in Milan (Italy). The cathedral stands tall over the city in Piazza del Duomo with its magnificent Renaissance dome designed by Filippo Brunelleschi. You can recognize this dome from anywhere in the city. The cathedral is named in honor of Santa Maria del Fiore.

The Cathedral

The cathedral was begun at the end of the 13th century by Arnolfo di Cambio and the dome, which dominates the exterior, was added in the 15th century. The exterior is covered in a decorative mix of pink, white, and green marble. It is just amazingly beautiful!



The interior is plain, cold, and stark. The mosaic pavements (pictures below) are something I love to photograph.


There are no masterpiece paintings in this Duomo except the magnificent fresco ceiling. It is hard to imagine it took two centuries for the cathedral to be considered complete. The star attraction within the cathedral is Giorgio Vasari‘s frescoes of the Last Judgment (1572-1579)

A picture of the back of the church shows a clock above the entrance. It was designed in 1443 by Paolo Uccello in accordance with the ora Italica, (where the 24th hour of the day ended at sunset) and it still works today!

We have been very lucky to visit Florence several times. Each time, there is scaffolding somewhere around part of the exterior for cleaning. I think that by the time they go around this enormous complex, it is time to start all over again! Not sure anyone will ever have a picture without some scaffolding and screening in it.

The dimensions of the building are Building area 8,300 square meters (89,340 square feet), length 153 meters (502 feet), width 38 meters (125 feet), width at the crossing 90 meters (300 feet). The height of the arches in the aisles is 23 meters (75 feet). The height of the dome is 114.5 meters (375.7 feet).


Brunelleschi’s Dome

Most people are aware that the dome consists of two interconnected shells. It is actually a shell within a shell and was erected between 1418 and 1434. Filippo Brunelleschi entered his design in a competition in 1418 but was only accepted after much controversy in 1420. The dome is capable of withstanding lightning and earthquakes and has a diameter of 149 feet or 45.5 meters. It remains the largest brick dome ever constructed. It is 463 steps to the top and worth every painful step; look at the views from the top!
