The Free State of Thuringia (Thüringen) is a former GDR state in central Germany, known as the "green heart" of Germany since it's covered with dense forest, is definitely not the most popular part of this country. I'd guess that most international visitors to Thuringia visit the former site of the Buchenwald concentration camp or are literature mavens who want to see Goethe and Schiller's Weimar. Sadly, this state is also infamous as a center of Neo-Nazi activity.
