Mura cittadine

The Walls of Naples, now visible in a few remnants, embraced a perimeter equal to the size of the old center. The Greek Walls are arranged along the edge of the plateau on which stands the city and became true and proper defensive ditches, contributing to the reputation of Neapolis which impregnable city. The blocks were extracted from the quarry of Poggioreale. The city had at the time "pincer" doors at the ends of the two decumani. The Greek Walls have two building phases: the first at the end of the sixth century BC (connected to the foundation of Neapolis) and the second to the fourth century BC (to be connected to the Samnite War). The dry wall tuff built by the Greeks, was altered in Roman times with a reinforcement blocks in piperno. This city Wall, famous for its power needed very few changes in the Byzantine era. Belisario introduced the polygonal towers. In Angevin period, military interventions was massive: the Walls were restored, reinforced and expanded southward. In the Aragonese period, the city was provided with twenty-two powerful cylindrical towers, moats and large bridges for access to the gates. Of the latter, they are preserved Capuana and Nolana Gates, with their side towers. Originally they were 27, most of which turned towards the sea. Finanziere Wall is the latest example of the city Walls: built by Ferdinand I in 1824, was designed by Stefano Gasse. It presents 13 duty barriers and 35 checkpoints.
