The Norman Door “of the Cantons”, which you can watch here see, with the adjacent manor prisons and it giving access to the Norman neighboring quarter, to houses and streets, still retain its original features.
In 1500 it was forbidden to build houses near the city wall and only later it was given the permission.
In 1700 the Marquis Carafa, paid 100 gold coins to renovate the walls; the manufacturer had to be unique in order to guarantee the same aesthetic result in all parts of the city walls.
The Door “of the Canton” was transformed in 1700 into an access to the old prison, which is now the headquarters of the municipal hall.
In 1400, thieves were exposed in the space in front of the door, called “Ribellino” according to a law of the time, which required the public defamation.
