Beyond the famous sites of Pompeii, Herculaneum, and Oplontis, the Campania region around Vesuvius contains several lesser-known but genuinely rewarding sites: the medieval Castle of Lettere (free with a valid Pompeii ticket), the Bronze Age canal village of Longola di Poggiomarino, and the royal Quisisana Palace (now housing the Libero D’Orsi Archaeological Museum).
Most visitors to the Vesuvian area spend their time between Pompeii, Herculaneum, and Mount Vesuvius — and for good reason. But the wider Campania region contains a remarkable range of other sites that reward the curious traveller willing to venture slightly off the beaten path. The three sites covered in this guide are each genuinely different in character: a medieval hilltop fortress with panoramic views, a Bronze Age waterside settlement discovered accidentally in 2000, and a royal Bourbon palace that became a hospital and is now an extraordinary archaeological museum. None requires more than a half-day to visit, and all three are free to enter with a valid Pompeii ticket.

Castle of Lettere (Castello di Lettere)
What is the Castle of Lettere near Pompeii? The Castle of Lettere is a medieval fortress built in the 10th century by the Duke of Amalfi to defend the northern borders of the Amalfi region. Set on a hilltop in the Lattari mountains, it offers panoramic views of the Gulf of Naples and Mount Vesuvius. Entry is free with a valid Pompeii ticket.
History
Built in the 10th century by the Duke of Amalfi to control the northern passes through the Lattari mountains, the Castle of Lettere served as a defensive stronghold and, briefly, a small fortified village. Historical documents from 1030 and 1033 describe the settlement inside the walls — multi-storey houses, a cathedral established in 987, and a distinctive bell tower added in the 12th century decorated with inlays of grey tuff and yellow sandstone.
The castle’s trapezoidal shape and four surviving towers — the tallest serving as the keep — are clearly visible from the valley below. Its strategic position allowed Amalfitan defenders to monitor both the port of Castellammare and the full sweep of the Gulf of Naples, making it a key node in the coastal defensive network.
What to See
- The panoramic views: From the hilltop, you can see Mount Vesuvius, the Gulf of Naples, the Sarno Valley, and on clear days the islands of Ischia and Capri. This is arguably the best viewpoint in the entire region.
- The medieval towers: Four of the original towers survive, with the tallest (the keep) accessible to climb.
- The 12th-century bell tower: Its distinctive geometric inlay decoration — stars, crosses, lozenges in grey and yellow stone — is well preserved.
Practical Information
Getting there: The castle is in the town of Lettere, approximately 10 km from Pompeii. Accessible by car (15 minutes) or local bus from Castellammare di Stabia. Entry: Free with a valid Pompeii ticket (within 30 days of issue).
Longola di Poggiomarino
What is Longola di Poggiomarino? Longola is a protohistoric Bronze Age to Iron Age settlement discovered accidentally in 2000 during infrastructure works, 10 km east of Pompeii. It is remarkable for its canal-based layout — buildings constructed on small man-made islands between canals, similar to ancient marsh settlements in Iraq and Benin. It is now under the management of the Archaeological Park of Pompeii.
History
In 2000, workers laying new infrastructure in Poggiomarino unexpectedly hit
Excavations have revealed huts of perishable materials (wood and thatch) on the dry islands, with canals serving both as transport routes and repositories of organic material. The site functioned as a hub for craft production and trade from the Iron Age onward — metalwork, bone carving, glass paste, and amber working have all been identified.
Practical Information
Location: Archaeological Nature Park of Longola, Via Longola, Poggiomarino (NA). Approximately 10 km east of Pompeii by car. Entry: Free with a valid Pompeii ticket within 30 days of issue. Best visited as part of a full-day or multi-day Pompeii trip.
Quisisana Palace (Reggia di Quisisana)
What is the Quisisana Palace near Pompeii? The Quisisana Palace (Reggia di Quisisana) is a historic royal residence on the slopes of Mount Vesuvius in Castellammare di Stabia, 10 km from Pompeii. Originally built as a retreat for Charles II of Anjou in the 13th century, it now houses the Libero D’Orsi Archaeological Museum of Stabia, displaying 507 artefacts from nearby Roman villas.
History
The palace dates to the Angevin period of the 13th century, commissioned as a retreat by Charles II of Anjou. Its name — ‘qui si sana’, meaning ‘heal here’ in Italian — reflects its purpose as a place of rest and recovery, chosen for its elevated position above the Gulf of Naples. Extensively rebuilt in the 18th and 19th centuries, the palace hosted generations of Bourbon royalty, and its grounds were used by artists, writers, and musicians — most famously Giovanni Boccaccio, who drew inspiration from the palace for parts of The Decameron.
After serving as a hotel (Hotel Margherita, 1898), a military hospital in both World Wars, and a period of severe neglect following the 1980 earthquake, the palace was restored in the early 2000s and reopened in 2009 as the Libero D’Orsi Archaeological Museum of Stabia.
The Museum
The museum houses 507 artefacts from the excavations of the nearby Roman villas of Stabiae — including frescoes, mosaics, sculpture, and domestic objects of extraordinary quality. The multimedia presentation using modern educational technology makes this one of the most accessible archaeological museums in the region.
Practical Information
Location: Viale Manzoni, Castellammare di Stabia, approximately 10 km from Pompeii by car. Entry: Free with a valid Pompeii ticket within 30 days of issue. See our Stabiae guide for nearby Roman villa sites that pair well with a Quisisana visit.
Planning Your Visit to These Sites
All three sites are best visited as add-ons to a 2-day Pompeii trip rather than as standalone day trips. The free-entry policy with a valid Pompeii ticket makes combining them very cost-effective. See our 2-day Pompeii itinerary for how to incorporate them into a wider Campania visit.
For the major archaeological sites in the same region — Oplontis, Boscoreale, and Stabiae — see their individual guides for full visitor information.
