The Certosa di San Martino ("Charterhouse of St. Martin") 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.
Later, in 1623, it was further expanded and became, under the direction of architect Cosimo Fanzago,[1] essentially the structure one sees today.
In the ensuing decades the monks made several attempts to reestablish their charter house, with the last effort failing in 1866, when the state definitively confiscated the property.
