Jena is a town very rich on history and famous for its optical industry.
I believe it is not an unprofessional approach when you want to create a tourist guide and want to visit a place to collect available information and to find people who can help with advise.
I tried to do this when I planned a visit to Jena. I wanted to learn more details about the "Battle of Jena-Auerstedt" where Napoleon defeated the Prussians. I wanted to learn about the event where participants from many countries brought this battle back to live.
I wanted to get contacts to get a access to the famous optical museum, the planetarium and other attractions.
I had so much on my mind. Unfortunately, I did not get any response or only inadequate answers. For that reason I put this interesting town on the back burner. Please use the official information which exist on the Internet.
For Thuringia this kind of behaviour is not unusual. Obviously, former GDR management style is still practised. On the other hand cities like Gera, Weimar and Mühlhausen provided excellent support by providing information and pictures. For that reason I will spend more time in Weimar whenever we visit Thuringia again.
