Where can you find Swiss heritage sites of national importance? Federal Inventory ISOS (FOC)
The Inventory of Swiss Heritage Sites (ISOS) designates and documents the most valuable sites of national importance. It makes it possible to understand the history and identity of sites and is thus an important basis for quality settlement development.

Work on the ISOS began in 1973 with the development of a suitable method for cataloguing sites – the ISOS method. In 2016, the Federal Office of Culture (FOC) updated this method and adapted the presentation of the inventory in line with GIS technology.

This layer presents the site records of the ISOS sites. It is updated annually.
