L'architettura fortificata nella cultura ingegneristica dei secoli XVIII e XIX.

Although during the eighteenth century the bastion fortifications gradually give way to the entrenched fields due to the rapid evolution of firearms with the diffusion before the iron bullets, then the explosive ones, among the technicians, architects and engineers, the diffusion remains. of an architectural culture still largely impregnated with fortification art. Although during the eighteenth century the bastion fortifications gradually give way to the entrenched military camps, due to the rapid evolution of firearms with the spread before the iron bullets, then explosive projectiles, among the technicians, architects and engineers, is still widespread an architectural culture largely impregnated with fortification art. As well as the battlements and towers, the ramparts that flank the baronial palaces rather than preparations intended for defense, become a symbol of feudal power which at its origins was linked to the exercise of arms. Even in urban planning culture the design of the cities remains strongly linked to the structures determined by the organizational needs of the defense of the fortress cities such as for example. they were Palmanova, Valletta or Carlentini. So for example at the end of the seventeenth century two Sicilian cities of new foundation placed near the sea, Santo Stefano di Camastra and Avola, the urban design is a function of an outer rampart that in reality then in both cases was only summarily outlined with a low and a simple wall, completely inadequate to support even a simple raid of armed bands or pirates.
