Old National Maps
Georeferenced old National Map 1:25,000 / 1:50,000 / 1:100,000

Already from about 1900, the first tests for new map series of Switzerland were carried out. The 1935 Federal Act named the new and still used National Maps as the official map series of Switzerland. They supersede the earlier Dufour and Siegfried Maps.
All editions are preserved in our Map Collection. The National Maps do completely cover the country in the largest as well as the smallest scales.
