The special position of the Spluga Valley has favoured the passage of man since prehistoric times: the melting ice and natural pathways facilitated passage over the Alpine pass from the very beginning.
Over the centuries, the Spluga Pass became one of the most fortunate routes in the Alps, determined by commercial and economic interests and also by its strategic-military importance. The routes of Roman antiquity and the Middle Ages routes already passed through Spluga, the Upper Rhine and Chur to reach the important Danube towns. This is also where the famous Lindau bus, which has been running from Lake Constance to Milan since 1823, used to stop.
