Physical insitute with observatory by Trekki
A closer inspection of the physical faculty is something you might like to do if you are interested in physics or geophysics. It was here where Alfred Wegener was working (1909-1919) and it was here where he first published his theory about what was only later recognised as facts: plate tectonics. Physics is located in Renthof, which is on the way to the castle via the ?secret path? or from Wettergasse onward up the hill (behind the statue of Christian). The building on the right (northeastern) side is the one where the memorial plaque to honour Wegener is located and also the one with the observatory (for weather rather than for astronomy, main photo) is mounted on top. But the main building (photo 2) is also interesting despite its rather plain architecture. It has lovely relief work and statues at the façade. I consider myself very lucky to have had my lessons in physics here in this building, in an auditorium of the old style (half round and steep).
The department of physics is well aware of their history and tradition and one of the rare faculties in Marburg which really takes care of and wants to attract foreign students ? their website has a very much extended English version (see link below). No wonder that the students who are responsible for the setting up of camera obscura at the castle have made an English flyer for this as well. Congratulations to the foresight and innovation of these guys :-). In case you are interested in physics, read the fascinating 28 pages pdf about history of the department of physics.
