What is Pozzuoli known for?

Third-largest Roman amphitheater in Italy at 147 by 117 meters, begun under Vespasian and finished under Titus, with intact underground machinery. Slow ground-level shifts of the Campi Flegrei caldera, first proven by mollusc borings on the Macellum columns; alert level raised in 2023. Largest commercial port of imperial Rome despite being 150 miles distant; the Apostle Paul landed here on his way north.

When is the best time to visit Pozzuoli?

May–Sep. May through September is the working season for Pozzuoli, with June and September the easiest months. Sea temperatures rise into the mid-twenties, and the open-air sites stay accessible without afternoon heat closures. July and August are hot and crowded; the Anfiteatro and Macellum work best in the first morning slots. The Campi Flegrei alert level was raised in 2023 and bradyseismic uplift continues, occasionally producing tremor swarms that locals notice but do not close the city for. Winter is mild and rainy. The patronal feast of San Procolo falls on 16 November. Ferry traffic to Procida and Ischia leaves from the port year round.

Pozzuoli is a comune in the province of Napoli, Campania region of Italy, about 19 kilometers from Napoli.

Pozzuoli

A Roman port on a volcanic caldera, the Greek Dicearchia and the Roman Puteoli, where a market's columns first proved that the ground itself rises and falls.

Why come

Pozzuoli sits at twenty-eight meters on the rim of the Campi Flegrei caldera, fifteen kilometers west of Napoli. Greek refugees from Samos founded the city in 531 BC as Dicearchia; Rome took it in 195 BC and renamed it Puteoli, a name the port kept through its centuries as Rome's busiest gateway by sea. The old town and the working town are not the same ground.

Rione Terra, the headland acropolis, was the city center for both the Greek and Roman settlements before it was evacuated in 1970 and reopened only piece by piece since. The rest of Pozzuoli has grown around and below it, on a caldera that does not hold still: the crater above town still vents sulfur, and the crust beneath the whole area continues its slow rise and fall, watched closely enough that the alert level was raised again in 2023. A port city built its wealth on ground that was always going to move under it, and the town's oldest quarter has spent the last half century learning to live with that fact rather than escape it.

What to see

Anfiteatro Flavio
The cage chambers and lift machinery beneath the arena floor survive largely intact, giving a rare view of how the underground works of a Roman amphitheater actually functioned.
Macellum (Tempio di Serapide)
A market building long misread as a temple to Serapis. The three marked columns still stand at the center of the floor, close enough to touch.
Rione Terra
The headland acropolis and original old town, evacuated in 1970 after a bradyseismic crisis and reopened only in stages since.
Solfatara
A crater above town venting sulfurous steam, mud pools and fumaroles, closed to visitors since an accident in 2017.
Castello Aragonese di Baia
A late-fifteenth-century fortress on the next promontory toward Bacoli, holding the Museo Archeologico dei Campi Flegrei since 1993.
