Florence Cathedral (Duomo di Firenze)
First opened in 1436, Florence's most famous landmark, the Duomo (or Cattedrale di Santa Maria del Fiore) is a must-see sight in the city. Filippo Brunelleschi's red-tiled dome is a wonder all on its own, but the architecture is as impressive inside as it is out. Climbing to the top of this stunning cathedral gives you great views of the city, too.
Check ticket availability
Tiqets was easy to use and we only had to wait in line for 3-5 minutes being being let in. Although it is more expensive than booking through the Duomo ticket office, it was simple and great for us as we booked last minute and were not able to get suitable times with the normal ticket office.
