What you can't loose of the "Duomo" is the roof: church spire, spire,gargoyles, statues, flying buttresses and so forth up close, AMAZING!!!!!!!

A breathtaking sight and a must-see if in Milan.  The Duomo cathedral is the symbol of Milan.  It's also the real centre of Milan - all the roads radiate out from the Duomo at its heart.  The huge plaza outside it is a meeting place, a place for strolling, watching other people or just walking across, or sitting in one of the cafes along the edge, and just enjoying the view.

It is renowned for its size (it is the third largest Catholic Church in the world after St Peter’s in Rome and the Seville Cathedral) and for its many statues (more than 3400). Its construction probably started in 1386 and  took almost 600 years to build. At the time it was built it could hold the entire population of Milan, 40,000 people. Its predominant style is late Gothic, but with elements belonging to the Romanesque tradition, such as for example the “hut” shaped facade”. The exterior is striking with its many spires and statuary - the interior is just massive. 

Entrance to the church is free except for groups over 4 people (5€ fee, rental of audioguide is mandatory and included in the price). More info: Groups

Note: There is a fee (2€) for taking picture. Info here http://www.duomomilano.it/en/press

Note: you will not be allowed to enter into the Duomo if you are dressed inappropriately (e.g. legs or shoulders uncovered).  However, there is no dress code for the roof.

Going up onto the roof of this wonderful Italian Cathedral is strongly recommended as a must-do. The entrance ( Duomo info point) is located to the left of the Duomo entrance. You can climb the many stairs to the roof for 7€ (250 steps) or take the elevator for 12€ (less if you're a 'senior citizen'.  Well worth the price to see all the gargoyles, statues, flying buttresses and so forth up close, and a view of the city and beyond.  On a clear day you can see all the way to the Alps.  Reservation on line and in advance is not needed

For times and prices/reductions, combined tickets with the access to Baptistery of San Giovanni and the Treasure or guided tours, please visit  Duomo of Milan official page. Sometimes, inside the Duomo or on its roof,  concerts or  exhibitions take also place.
