The existing ruins in piazza Ronchi, near via Prenestina, are probably pertinent to a Roman cistern built in brick, with the use of yellow and red bricks and an inner core in tuff flakes.
The cistern was supposed to have a rectangular plan and only two walls remain in part for a maximum height of about two meters; in a corner there are parts of the cocciopesto coating which was used to waterproof the walls and which allowed the ruins to be identified as a cistern.
On the external walls there are a series of buttresses, while in one of the best preserved walls there is a door, or a window, with a travertine threshold, perhaps inserted in a second construction phase.
