Areas of Pisa
The city of Pisa is contained within its medieval walls, built in the 12th century and split horizontally by the River Arno which flows through it. Everything to the north of the river within the city walls is known as Tramontana and everything below the river to the south is known as Mezzogiorno. Apart from this north/south of the river distinction, there are four areas contained within the city, two within Tramontana and two within Mezzogiorno. In Tramontana, the north western section is known as Santa Maria and the north eastern section called San Francesco. South of the river in Mezzogiorno we find San Martino in the south east and Sant'Antonio covering the south-western quarter.
