Piazza del Duomo di Pisa
Lots of people on the piazza getting the standard touristic picture.
With the baptistery in the forefront - in the middle ages you couldn't enter the church without being baptized so baptisteries were built in front of, and separate from the church.
Baptistery - The baptistery has amazing acoustics and sometimes one of the employees will show up their skills and the building by singing. You can sing a three part harmony ... solo. We were there while he did. You can see/hear it here.

The whole area is really touristic. You have about a ten minute walk from the parking area to the piazza and the route is lined with street hawkers, pickpockets, etc. They are not allowed in the piazza.
The legend is that if you look at this column your significant other will remain faithful. The guide joked that the spell only holds for 24 hours, so it is a good thing she is there every day.
Nave
The interior has an Islamic feel.
The pulpit was designed by Giovanni Pisano around 1300. While this was done more than a century before the Renaissance Michelangelo traveled here to draw inspiration from it.

This lady can't walk, is in a wheelchair, and firing up her cigarette. I thought it was quite the commentary.
The excursion I was signed up for including both Pisa and Lucca and was a disaster. Because of the time management problem we actually left people in Pisa who didn't make it back to the meeting spot on time, and the guide made some fairly awful racist comments about some of the street vendors - telling us not to be afraid of the "black Africans" they wouldn't hurt us, and actually were helpful in letting the guides know when pickpockets were around. The whole thing just left a bad taste. BUT, here is what you should take away from my experience. Pisa is more than just a leaning tower. It is a beautiful and amazing place. Please visit, and please resist the temptation to take the standard touristic picture of you pushing the tower into place.
