“Journey through time” viewer
What did Bern look like in 1900, or the banks of Lake Zurich in 1864? How far did the Aletsch glacier reach 20 years ago?
To answer these questions and highlight national heritage in country maps, swisstopo has developed a viewer for topographical maps allowing a journey through time.
Almost 175 years of cartographic history of Switzerland are available.
The Federal Office of Topography was founded by General Guillaume-Henri Dufour in 1838. It published its first map of the region between Vevey and Sion (n°XVII) in 1844. By 1864, all of Switzerland had been mapped.
