The study relating to the town walls of Nola (a city near Naples) is one of the most interesting among those about the Neapolitan military architecture between the fifteenth and sixteenth centuries. The building phases of the defensive walls allow us to retrace two main moments of the Renaissance military architecture.

It is to say, from the original and most ancient example of a puntoni struts fortifications, about which we can relate thanks to the precious and detailed Ambrogio Leone de Nola’s description made at the beginning of 1500, to the renewed defensive rampart body designed by el comendador Luis Escrivà during the Toledian period. A thorough recon of the iconographic sources, the regarding of the specialistic historiography, the contemporary theoretical assumptions and, most of all, a thorough recon of the still visible traces in the urban fabric and those emerged during the recent archeological investigations enable us to propose a structured theory about the building of the walls of Nola.
