In Naples, the people are very fond of this tradition, and there is also a road where they sell the parts people need.
In Naples there is also an interesting museum at the Certosa di San Martino.
In Rome, the tradition is a bit 'different but we say some.
In the ancient church of SS.Cosma and Damiano, not far from the Forum, you can see, almost all year, a beautiful nativity eighteenth-century, Neapolitan style.

Other interesting nativity scenes are usually set up in many Roman churches and always has a quite successful one proposed in Santa Maria in Aracoeli.
On the subject of the Nativity we mention however two important works: the frescoes by Pinturicchio in the church of Santa Maria del Popolo and the nativity scene sculpted by Arnolfo di Cambio in 1291, now visible in the museum of Santa Maria Maggiore.

Many inhabitants of Rome still make the Nativity scene at home and sometimes they build them with pieces of plastic.
There are also very modern representations.

Finally, almost every year at Christmas time, is an exhibition near the church of Santa Maria del Popolo.
