Along the river Marta and its tributaries the first settlements on today's Tuscania, as early as the Bronze Age saw the light.
The different necropolis discovered in the area indicate that there were seven distinct settlements from the seventh century A.C.
Unlike elsewhere, in Tuscania the aggregation of villages into a single large settlement happened very slowly, until it stabilized in the late fourth century A.C.
In the most archaic stages Tuscania was part of the territory of neighboring and more important Tarquinia that greatly influenced the traditions and the local culture.
Concurrent use of tombs of different shape include Tuscania in the soÂcalled "culture of rock tombs of the first archaic period", along with other centers such as Blera, San Giuliano and San Giovenale.
There are also signs of other cultures, such as Vulci, Volsinian, the Chiusina and Greek, as shown by significant import ceramic finds.
During the third century A.C. Also in Tuscania the Romans arrived and gave birth to the tribe "Stellatina", the vast territory surrounding the control point that will become increasingly important after being raised to the ancient Roman Via della Via Clodia.
At the beginning of the Middle Ages Tuscania became an important diocese and its bishop had civil powers on the territory for centuries and centuries. Once the Bishop was ousted by civil powers, Tuscania started to live internal power
struggles, until in 1300 it was occupied by forces of the Capitol, going so under its direct control. Then in 1400, it fell under the control of the Papal State until the capture of Roma in 1870.
