Etymology of Avisio

The name "Avisio" is documented around 1050 AD as supra fluvium qui vocatur Auis, and in 1200 AD as ponte Avisi. It is most likely derived from the Gallic word abisjo, meaning "watercourse," which itself originates from the Proto-Indo-European root abì, meaning "water".

Course of the Avisio River

The Avisio River originates from the Marmolada, flowing through the Val di Fassa, Val di Fiemme, and Val di Cembra valleys.
