Pisa is all about the Leaning Tower. Half a Day is sufficient to see the city.
From The train station, take the main artery Corso Italia which is the pedestrian passage to get to Piazza Dei Miracoli. By there you have the Piazza del Duomo, it is a UNESCO World Heritage Site since 1987. The Piazza is the place where all the Pisa must see are including the famous leaning tower of Pisa that “had a great influence on monumental art in Italy from the 11th to the 14th century.” You can go inside the tower and while going up you can feel the tower is leaning. You will always be attracted to the walls which make the walking up the stairs a little bit difficult. From the top of the tower, you will have an amazing view of the Piazza and its monuments, the Cathedral, the Baptistery and the Cemetery as well as the whole city.
Exit the Piazza to go see the Cathedral of Saint Caterina d’Allessandria and you can stroll in the park in front of it.
Then head the other main square, the Knights’ Square. On that Cavalieri square, that used to be the political center of the city, you have the Church of Santo Stefano dei Cavalieri, Palazzo de Corovana, and the Clock Tower. Stand in the middle to have a 360-degree view of that beautiful Piazza.
Finally walk back towards the Arno River. Take a leisure walk along all the colorful houses by the river. By the rover, you will see a very small Gothic church. It is the Church of Santa Maria della Spina. It is very unusual to see that small church in the middle of the city between the River the houses. Unfortunately, we can’t go inside of it.
Pisa is a small walled city and if you are on a busy tourist schedule, it is the perfect city to slow down and just enjoy Italy.
