The Angevin foundation, Aragonese rebuilding and Renaissance arch record successive claims to Naples as a capital. Chapels, halls and later civic museum use transformed the fortress without erasing its military mass.
Piazza Municipio is an archaeological and transport field as well as a public square. Metro construction, excavated harbour evidence and new pedestrian connections reveal how the ancient and modern waterfront moved.
Molo Beverello and Stazione Marittima remain departure and operational zones. Ferries, cruise passengers, freight, police and port workers have priority; access rules and schedules are live infrastructure, not incidental inconvenience.
Begin with the castle’s exterior and controlled interiors, cross Municipio through open routes, then observe the port from public edges without entering restricted operational areas.
