The remodel not only offers a chance to display over 200 works of art in their best light, but it also features an entirely new design catered to showing off the history of Florence's most famous cathedral. Guests can now even view the many works part of the Duomo's history that were hidden away for restoration purposes.
But perhaps the most significant change made was to the overall structure of the building and the way the artwork is displayed.

Special care was given to make sure that viewers would have the opportunity to view the different pieces at their finest; spatiality was of the utmost of importance to the designers, and visitors can now see each work to its full advantage.
The best example of this is the newly constructed Hall of the Antique Facade (or the Sala dell'Antica Facciata, in Italian). It is a life-size reproduction of the old Duomo facade by Arnolfo di Cambio created in the 1200s.
You'll find a stunning wall ahead of you. It transports you back to an earlier time in Florence's history and a previous type of architecture unseen on the Duomo's facade today.
The facade and the new layout of the building aren't the only new changes guests will see. All of the artworks have been completely restored, offering visitors a chance to see them as they would have been when each work was finished.
Among some of the famous works that you can visit include Donatello's haunting "Penitent Mary Magdalen" and "Cantorie" by Luca della Robbia.
It would be a shame not to see Ghiberti's original baptistry doors displayed at their finest. Seeing them in their glory is a breathtaking moment you should experience while touring the Opera del Duomo Museum.
A final peek at Michelangelo's "Pieta del Duomo" rounds off an incredible visit and a chance to see these works as they were meant to be seen.
You can enter the museum for 15 euro. Admission prices also include entry to the Baptistery, Brunelleschi's Dome, Giotto's Campanile and the Crypt of Santa Reparata.
Make sure to ask for a reduced price if you're a student or senior citizen. In that case, you can see all this for a total of 6 euro.
