Pisa is best known for the world famous Leaning Tower, but those who come here with their mind already made up that the Tower is the only thing to see may miss the rest of the architectural and artistic marvels of this beautiful city.The long walk from the Campo dei Miracoli to the train station is run through a pedestrian mall with many interesting sights, shops, and restaurants. The best way to visit Pisa is walking in the street, as the city center is very small, and enjoy the sight and the atmosphere.Pisa will not be Pisa without the University. The city is animated by the students, which organize parties, shows, cultural events, or fills the central street of the city at night. The University of Pisa has 60.000 students, not all live in Pisa but since Pisa has about 100.000 inhabitant, we can say half of the population is made of student: you can see it by yourself if you quit strictly tourist places and walk around in the city in place like Piazza Dante, Piazza Garibaldi, Borgo Stretto.Pisa is a safe city, you do not need to worry about your property or person (except for some zone at night, such as the area surrounding the stations). However you should take the obvious precautions (like, if you stay in a very cheap hotel, take your valuables with you) and watch out for pickpockets in the touristy areas. http://wikitravel.org/en/Pisa
