"Al Aviöler" - "by the bee house" - comes from Rhaeto-Romanic, which was the language of the original inhabitants of the Oberpaznaun and was spoken well into the 17th century in some parts. The Rhaetians came from the neighbouring Unterengadin and found new pasture land in Paznaun. All the names of towns, villages and meadows are Rhaeto-Romanic to this day, bearing witness to this unique vernacular.
As a result of the influx of people from the Walser Valley in the Swiss canton of Wallis, the Rhaeto-Romanic element was eventually almost completely displaced. In the Swiss Engadin, it has remained the vernacular to this day.
