If you have the energy the climb to the top of the dome (436 steps) affords memorable views. The entry to the Duomo is free but there is a fee to climb the dome.
In the middle of the bridge there is a gap between the shops, enabling you a great view of the river and the buildings on opposite banks.
It is a great place to have a coffee or gelato, do some people watching and write a post card or two.
In the entrance fee the visit of the monastery and tomb are included.
