Beneath Fermo's tidy hilltop center lies an entirely different kind of monument: thirty interconnected chambers, covering some 2,200 square meters, that stored the Roman city's water supply and survive today in near-perfect condition.

Built under Augustus, the vaulted halls still collect a few centimeters of rainwater on the floor, which mirrors visitors' lamps back at the ceiling and turns a straightforward engineering tour into something closer to a light installation. The cisterns are seen on guided visits, and the constant cool underground temperature is a relief in a Marche summer.

Four things worth finding

If you see nothing else, see these.

  1. The thirty chambers in three rowsRoman waterworks, about the time of Augustus

    About 2,200 square meters of underground halls, arranged in three parallel rows, gathered rainwater for the whole city.Beneath Via Paccarone

  2. The waterproof plaster and the concrete wallsOpus signinum and opus caementicium

    Look at the lower 70 centimeters of the walls, still lined with the waterproof plaster that kept the tanks tight.Along the chamber walls

  3. The lead pipes and the ventilation shaftsRoman engineering

    Fifteen aeration and inspection shafts, drainage channels and two lead pipes of different sizes still show how water was distributed to the town's fountains.Inside the chambers

  4. The small cisterns under the town hallRoman, smaller and higher

A summer afternoon, when the underground cool is most welcome after Fermo's hilltop heat
Getting there
The entrance is in Fermo's historic center, near Piazza del Popolo, easily reached on foot; Fermo itself is a short drive from the coast at Porto San Giorgio.

A single ticket for the cisterns costs €4; a cumulative ticket covering Fermo's full museum circuit for one year costs €9 full, €7 reduced (ages 14-25, groups of 15+); free under 14, for visitors with disabilities and ICOM members. Last updated September 2026. Prices change, so check the official site before you go.

Time your visit for one of the guided tour departures rather than just showing up: the cisterns can only be seen with a guide, and arriving between slots means waiting on underground stairs with nowhere to sit.

Good to know

How long should you spend at the Roman Cisterns of Fermo?

About 45 minutes is enough for the guided visit through the chambers. It is a compact site, but the scale underground is what surprises people.

Where do you enter the Roman Cisterns of Fermo?

Today you go in through the Museo Civico Archeologico, in the former Dominican convent beside the church of San Domenico, and then continue underground. The original Roman stairway is visible only from inside.

Are the Roman Cisterns of Fermo worth visiting?

Yes. At about 2,200 square meters they are unusually large for Italy and in near-perfect condition, and the underground chambers stay cool on a hot Marche afternoon. Check the Fermo museums site for how guided entries are run.
