Walls, towers and gates Porta Napoletana Porta Napoletana was built in 1511 in alignment with the ancient defensive wall circle of Velletri. On one of the door jambs there is an intimation that attributed to the Door a real function of a customs barrier. During the eighteenth century the structure underwent several changes, such as the reinforcement of the two side towers of a semicircular shape.

It is characterized by the Lombardy-Gothic style and stands for about 50 meters in height. The facades are distinguished by eight windows each, adorned with green majolica bowls.
