The Tower of Nisida as centre of 17th century fortified Naples system

The paper investigates the territorial layout of the fortified system of Naples that developed during the Spanish Vice Kingdom in the 16th-17th centuries. Both existing castles and towers, and constructions built for the purpose, were included in the system. The Tower of Nisida is one of the existing ancient towers that became part of the impressive 17th century defense system of Naples. The study focus is on the strategic importance acquired by Nisida and its Tower in those years, when it became a key location in the fortified system, both evidencing its cruciality through the study of the field of vision that widens from the location and dealing the issue with the point of view landscape and territorial defense, recalling the concept that the defense architecture is part of architectural heritage
