The city is completely surrounded by medieval walls and is still placed on the ancient plant with the tracing of the Francigene and with the old Florentina road.
On the top of the hill, where San Gimignano was built, there are the two main squares: piazza della Cisterna is a triangle bordered with buildings and piazza del Duomo with the City Hall.
San Gimignano has been declared from the UNESCO as humanity worldwide patrimony and is famous all over the world for its towers, from which it takes the nickname "city of the beautiful towers", for the wonderful surrounding landscape and for its products: the wine "Vernaccia" DOCG and the saffron.
