Those who are allowed to make drawings for the Gotthard line here in the open air in 1875 should themselves lucky! The tunnel workers toiled in the often far too stuffy pits in the north and south. The construction company Favre allows this and numerous other
Conrad Gessner (1516-1565), a polymath and Zurich city doctor, lived at a time when traditional knowledge was joined by a wealth of new experiences. Not only did the discovery of America open up unknown places, but also unfamiliar flora and fauna. At the same time, many ancient
