In the Northwest, Venosta Valley lies at the frontier between two countries, the areas of Engadin and Val Müstair in Switzerland and the Inntal Valley in Austria. Being located at a tri-boarder area has shaped the country and the people of Venosta Valley throughout history. Since 2007, the border regions of the three countries have been successfully working together through the transnational program Terra Raetica.

The passes of the Upper Venosta Valley define the borders between the German-speaking Venosta Valley and the Rhaeto-Romanic speaking area of Grisons. Romanic was also spoken in Venosta Valley until the time of the Reformation, and in partly until as recently as the 19th century, meaning that many field names still have Raethian and even Celtic origins.

Today, there still exists the common Alpine Road of Romanesque Art, which boasts many treasures in the form of unique architectural gems on every side of the mutual borders.
