Mel has a very ancient history: its origins are paleo-Venetian. Subsequently between the V and III century BC. the Gauls settled there and left traces in the toponymy of the area.
As with the rest of the valley, the Zumellese area also became part of Roman history. Furthermore, the territory was crossed by the Via Claudia Augusta Altinate, a remarkably important road that connected the Po Valley with the Alps.
With the end of the Roman Empire the barbarians took over. The presence of the Lombards is significant, leaving traces in places of worship such as the church of San Donato.
With the Middle Ages numerous manors arose to defend the valley and the communication routes. The most important was certainly the Castle of Zumelle, the main pivot of the defensive system of the entire Valbelluna. Mel remained Venetian until the arrival of Napoleon who upset the whole administrative system. In the nineteenth century the territory suffered the same fate as the entire valley: the two world wars brought a heavy toll of Zumellese human lives.
In the 1950s it depopulated due to emigration. With the economic boom the country changed from being totally agricultural and peasant to its current form, with important industrial and artisan companies.
