Preserving the legacy of Switzerland’s landscapes
During the past 175 years, swisstopo has been documenting Switzerland’s topographic development. Lea Dauwalder is well acquainted with the diversity of this historical heritage. She is responsible for the restoration and conservation of swisstopo’s map collection – a manual task that calls for a great deal of precision and attention to detail.

Historical maps
The swisstopo map collection is a unique cultural treasure comprising all first editions and revised versions of the official Dufour Map, the Siegfried Map and the series of national maps. The collection also contains a variety of documents, including handwritten items. All editions of the maps produced in analogue form can now be obtained in digital form or conveniently viewed chronologically in swisstopo’s map viewer.
