About Acquarossa
For the time before the Archaic Etruscan period, the material found indicates a more or less scattered habitation. Remains of huts from the final phase of the Iron Age were found on the highest point of the acropolis (zone K), but pottery of the same kind as that associated with the huts has been found also in other parts of the site.
The Archaic Etruscan habitation, with roughly square houses, is the most important part of the history of the acropolis. It began c. 625 or somewhat earlier and lasted until 550 or shortly after. Acquarossa at that time seems to have been a real city with numerous inhabitants.
Following the destruction of the city, the site seems to have been abandoned before it was inhabited again later on. The last phase of habitation is the Roman one. Fragments of Roman tiles are to be found all over the acropolis, but architectural remains are present only in a few spots. Among these are the foundations of a Roman villa and one stretch of a subterranean aqueduct.
