The Via Claudia Augusta is an ancient Roman road, which linked the valley of the Po River with Rhaetia (encompassing parts of modern Eastern Switzerland, Northern Italy, Western Austria, Southern Germany and all of Liechtenstein) across the Alps.
The route still exists, and since the 1990s increased interest in long-distance hiking and cycling have made the German and Austrian stretches of the Via Claudia Augusta popular among tourists, with the result that modern signage (illustration) identifies the revitalised track. Since 2007, the Giontech Archeological Site, in Mezzocorona/Kronmetz (Italy) serves as the Via Claudia Augusta International Research Center with the support of the Foundation Piana Rotaliana and the Government of the City of Mezzocorona/Kronmetz.[1][2]
