Pisa
We took a half-day trip to Pisa while staying in Florence. It is only about one hour away by train through scenic Tuscany. There really isn't much to see in Pisa other than the Leaning Tower. There are some colleges or universities there, but we spent all of our time at the tower. Recently, it had been under construction to stabilize it -- not "straighten" it like so many people have tried to tell me. They up-righted it by only a mere 2 centimeters of overhang at the top -- nothing anyone could notice -- but that was enough, along with reinforcing its foundation, to stabilize it and keep it from falling. If you have a decent monitor, you should be able to read more about it by clicking on the image of the sign at the bottom-left of this page. The construction had just been completed. In fact, just two days after we visited, there was to be a public celebration of the completion. Its surface still needs to be cleaned, and I think there's some minor inside work to be done, but the tower is scheduled to be re-opened to the public around November, 2001, but advance reservations will be required.
