Naples - Carthusian Monastery (Museum)

To the east of the Castel Sant'Elmo in Naples is the former Carthusian monastery of San Martino (1325; rebuilt in the 17th century), with the Museo Nazionale di San Martino. Notable features are the church, richly decorated with marble and pictures of the 17th and 18th centuries, the sacristy, the treasury, the Chiostro dei Procuratori and the main cloisters, with 60 columns of white marble.

The museum contains porcelain, cribs, including the Presepe di Cuciniello, a state coach of Charles III's reign (18th century) and relics of the history of Naples and southern Italy in the 18th and 19th centuries.

From the room known as the Belvedere there are superb views of Naples, its bay and Vesuvius extending to the Apennines.
