About two kilometers from the center of the city, on the eastern suburbs is the 13^th century Gonfienti village. In 1997, during the excavations for the construction of the Central Tuscany Interport, a very large and important Etruscan city was discovered in this area.
During the excavations a large lattice of roads was found, wide up to 10 meters with drainage channels and large sections of clay still preserved, but above all there were also several dwellings, and in particular a large Domus (at least 1270 square meters).
Domus is made up of a series of rooms that overlook a quadrangular courtyard with a circular well and a complex hydraulic system for water outflow. Domus has the typical structure of other known Etruscan houses, such as in Marzabotto. During the excavations, particularly valuable archaeological finds were recovered, including Douris' Cup or Kylix, Greek artist of that time.
The recent discovery of this Etruscan city (perhaps the largest in Tuscany) suggests that this was strategically located on the iron road from the island of Elba, from Pisa to the city of Marzabotto and the Adriatic coast.
