Via Imperii, i.e. "Imperial Road", was one of the most important Reichsstraßen of the Holy Roman Empire. The old trade route ran in a south-north direction from Venice on the Adriatic Sea and Verona in the Kingdom of Italy across the Brenner Pass through Germany to the Baltic coast passing the following cities:
The cities on the route held the privilege of staple right, merchants were obliged to use the toll road and in turn enjoyed protection by the Imperial authority under the terms of the Landfrieden.
Parts of the historic route are today marked by the Italian Strada Statale No. 12, the Austrian Landesstraßen B 182 and B 177 and the German Bundesstraße 2.
