The white massive structure of Certosa di San Martino emerging from the green hill of Vomero is clearly visible from the low city. After the unification of Italy, the Certosa became a museum. It houses among the most important remains of the ancient culture of the Carthusian order, founded during the Angevine age by the most famous architects of that time. The itinerary includes the different sections of the complex, such as the one with nativity scenes, the naval section, the corridor of the carriages, the two cloisters and the rich Baroque church. 

The Certosa is closed on Wednesdays.
