This is a really impressive building on the outside, being located next to the Leaning Tower on the Campo dei Miracoli. It is the only building on this site which is free to visit.
We found the inside of the Duomo much less impressive. This was not helped by the fact that when we were in Pisa, you were only able to access the very rear of the Duomo with the vast majority of the inside area being cordoned off. It was not clear whether this was a permanent arrangement, but the atmosphere was ruined by the presence of two uniformed guards who appeared to be eager to apprehend anyone who tried to cross the cordon, or take photos.
Another small area of the Duomo was accessible for private prayer.
Overall, the Duomo inside was very disappointing. It is much better simply to take in the external views of the building.
