[EN] From the Middle Ages and up to the nineteenth century, the heritage of architecture for the defense in the territory of Alessandria in Piedmont constitute a coherent system of examples that weld the theory of handbooks with the practice of the construction, intended to protect places and cities in this region: Casale Monferrato, Alessandria, Gavi etc. From Sebastien Vauban to the "father Engineer" Vincenzo da Fiorenzuola and to Lorenzo Bernardino Pinto, Antonio Ignazio Bertola, Gaspare Beretta (and beyond) the presence of designs and achievements in this area is configured as authentic and tangible "anthology of models for the defense "in Europe, for which the writer has in place for twenty years a systematic scientific research. On this occasion, we will address the possibility of rebuilding, also virtually, those episodes in the territory as a whole, to arrive at a deeper understanding both for the disclosure, as for cultural tourism.
