Until the early Middle Ages, the historical events of the Zoldo Valley are unknown. Probabily, during prehistoric times this area was not inhabited on a permanent basis, and the same it happened in pre-Roman or Roman times. About this last period there are three inscriptions, around the Civetta, that could indicate the borders between the territories of Iulium Carnicum and Bellunum. For centuries then the Zoldo Valley was a border area and later the frontier between the territories of Belluno (to which it belonged) and Cadore.
The Middle Ages
As already mentioned, even the early Middle Ages were a mysterious time and the few recorded events are essentially legends. Maybe under the Lombards the first embryo of the system of the Rules appeared, lasting until the 19th century. Only in 1185 did a Papal Bull quote the Zoldo Valley for the first time, administered by the parish of San Floriano and dependent on the Bishop of Belluno. Then, the territory passed to Ezzelino III da Romano (1249), and then (1347) to the Avoscano. Shortly afterwards Louis 1 of Hungary assigned it to the Da Carraras. Other events finally gave it to Venice (1404) where it remained until the fall of that Republic (1797).
The Republic of Venice
When began the battles between Venice and the League of Cambrai in 1508, also many people from the Zoldo Valley gave their contribution to the victory of the Republic of Venice. From then Zoldo became prosperous thanks to forestry, which furnished timber for the Arsenal and the piles of Venice and above all the activity of iron-working.
Nineteenth and Twentieth centuries
When the Republic fell, the valley passed from France to Austria and vice versa, finally becoming Austrian. After taking part in the Risorgimento, Zoldo Alto, Zoppè and Forno di Zoldo became municipalities of the Kingdom of Italy (1866). In the meantime, modern industry overtook the traditional black-smith activities forcing many of the inhabitants to emigrate elsewhere in search of work as for example, ice cream makers.
