As the name suggests, Fontanelle is an area rich in springs and originally housed a rain forest of oaks.
The oldest human traces consist of a few stone tools that are now preserved at the Museum of Oderzo. Based on these, it is believed that the territory was crossed by Neolithic hunters from Montello.
In Roman times the area was certainly inhabited, given the proximity tomunicipium of Oderzo and the passage of a direct route to Serravalle. From this period are the remains of pottery, bricks and other material.
The importance of Fontanelle grew during the Middle Ages as the seat of a parish under the diocese ofCeneda, and with jurisdiction over the churches of Cimetta Codogné, Fontanellette, and Vallonto Visnà.
In this period the area featured a fraternity of Flagellants, based on that of Oderzo founded in 1313.
According to some sources in Fontanelle was home to a castle, with localization to the north-west of the capital.
