The Duomo, is another name for the Florence Cathedral, formally known as the Basilica di Santa Maria del Fiore, a Roman Catholic church in Florence, Italy. It was built on the site of the old cathedral of Santa Reparata starting in 1296. The Duomo was consecrated in 1436 and was once the world’s largest church, accommodating 30,000 worshippers.
The Florence Cathedral has many significant features, such as its stained glass windows, its ornate green, red, and white marble facade, and its collection of paintings and statuary by Renaissance masters. The dome, an impressive feat of architecture, was designed by Filippo Brunelleschi between 1420 and 1436.
