Market square, Jena.
Introduction
Thuringia's second largest city, Jena is the university town where Carl Zeiss and Ernst Abbe laid the foundation of modern optics.
Defaced by GDR city planning, Jena is rather unexceptional from a touristic point of view, apart from a handful of specialised museums linked to the local history (optical instruments, glass, phylogeny) and a Goethe Memorial.
