The main points of the project are:
- Natural light and ventilation for the MM users, thus making more liveable the Duomo station
- A lower level plaza, giving access to the MM and the Ark
- An archaeological area: not only does it gives access as well to the MM but it realizes a pleasant landscape design and a cultural achievement, allowing also to reach the ancient Baptistery, which is rather unknown today
- A new underground station MM + buses + taxis + tourist coaches, which will allow the square to be completely free of traffic
- New commercial and cultural activities, associated to the Ark, with the purpose of enhancing its insertion into the square life.
