UNESCO: Certosa di San Martino

The Certosa di San Martino is a former monastery complex, now a museum, in Naples, southern Italy. Along with Castel Sant'Elmo that stands beside it, this is the most visible landmark of the city, perched atop the Vomero hill that commands the gulf. A Carthusian monastery, it was finished and inaugurated under the rule of Queen Joan I in 1368. It was dedicated to St. Martin of Tours.

In the early 19th century, under French rule the monastery was closed and was abandoned by the religious order. Today, the buildings house a museum with a display of Spanish and Bourbon era artifacts, as well as displays of the presepe—Nativity scene—considered to be among the finest in the world.
