- Giessen: Boat Tour on the River Lahn and Guided Tour of the City
A short bus drive will bring you to the starting point of the boat tour on the river Lahn. The Lahn is an important tributory of the Rhine and is flowing for the most part through Hesse connecting the two university cities Marburg and Giessen on its way. On the boat beverages will be served, and a tour guide will provide you more details on the river. Back at the landing stage, which is close to the city center, you will embark on a short walk (approx. 1,5 km) through the history of Giessen where Justus von Liebig founded the world's first major school of chemistry and became patron of the university, and where Wilhelm Conrad Röntgen, physics nobel prize winner in 1901 “in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him”, is buried on the old cemetry. At the end of the city tour you will be picked up by the bus(es) returning from Marburg at around 17:30.
