Museo Archeologico Nazionale

The museum was built around the Farnese collection, inherited through the Bourbon kings of Naples, and later absorbed almost everything portable that came out of the excavations at Pompeii and Herculaneum. What resulted is not a supplementary display case for those sites but the primary place their finest objects actually live — the ruins themselves are largely empty shells by comparison.

The building itself started life as a cavalry barracks and later housed the university before Ferdinand IV converted it for the royal collections in the 18th century. The Secret Cabinet, a separate room for erotic frescoes and sculpture recovered from Pompeii, was kept locked to all but special permission for most of the museum's history and only opened to general admission in recent decades.

Inside

What to see

The Alexander Mosaic, an extraordinarily detailed battle scene lifted whole from the House of the Faun in Pompeii
The Farnese Bull and Farnese Hercules, colossal ancient marbles from the Baths of Caracalla in Rome
Wall paintings removed intact from Pompeian villas, preserving colour and detail lost to weather at the sites themselves
The Secret Cabinet (Gabinetto Segreto), holding erotic frescoes, sculpture and objects from Pompeii and Herculaneum

Practical

Good to know

Visit before Pompeii, not after — the site makes far more sense once you've seen what was actually found there.
The Secret Cabinet has separate, sometimes restricted access hours and may require a small additional booking.
The collection is vast — budget more time than the building's footprint suggests, especially if archaeology genuinely interests you.

FAQ

Common questions

Should I visit before or after Pompeii?

Before, if possible. The museum holds the finest frescoes, mosaics and sculpture from the site, and seeing them first makes the ruins far more legible.

Is the Secret Cabinet included in the standard ticket?

Generally yes, though access hours or a small supplementary booking have applied at times.

How long should I plan for?

Two to three hours for a thorough visit; committed archaeology fans could easily spend a full morning.

Is it crowded?

Busy at midday in high season but rarely as packed as the archaeological sites themselves.
