Pisa was a great medieval city, but it was also home to the Renaissance genius, Galileo Galilei. Galileo was born in Pisa, became a professor at the university, and it was a lamp in the Pisa Cathedral, suspended high in the ceiling, that inspired Galileo's experiments with pendulums.
Leaning Tower of Pisa - Don't miss it. A friend writes," I'd expected the Leaning Tower to be a hokey tourist trap, but it was beautiful. The square surrounding the tower was crowded with tourists and local people taking the air. A few guys were having a relaxed pickup soccer game, and they let my son join them for a few minutes." And now, after years of restoration, you can climb up to the top of tower (minimum age for kids is 8 years old).
Duomo (Cathedral) and Baptistery - The Tower of Pisa is really just the bell tower for the Pisa Cathedral. When you step inside the cathedral, look up at that high ceiling and imagine that you're Galileo. The big rounded Bapistery has more of the white marble, inlaid with greenish black marble, a large font in the middle where baptisms were performed, and a gorgeous Pisano marble pulpit with a beautifully carved nativity scene.
Old town walls - The northwest corner of the Campo dei Miracoli is enclosed by sections of medieval town walls. Climb up the medieval tower for good views of all the buildings in the piazza. This tower is free, and there's no age limit, so this is a good alternative if your kids are too little to climb up the Leaning Tower of Pisa.
