Federal Inventory of Historic roads

The aim of the Inventory (Bundesinventar der historischen Verkehrswege der Schweiz, l’Inventaire fédéral des voies de communication historiques de la Suisse,  IVS) is to preserve and maintain these important witnesses from the past to the present. They shape the landscape and are often also outstanding cultural objects in terms of construction and architecture.
