The swisstopo map collection encompasses far more than the three well-known national map series. Among (and alongside) the more than 50,000 map sheets are some treasures and even unexpected finds. At this colloquium, we will show you a selection of these treasures, which have been preserved or rediscovered over the years. You will learn about the background of these items and have the opportunity to view a selection of them in their original form.
