Kochberg Castle used to be owned by the von Stein family; Goethe visited Charlotte von Stein there several times. 

As part of the 1000 Years of Weimar celebrations, the castle, which has been turned into a memorial, is opened to the public.

In this documentary, students at the Weimar music college give a celebratory concert at the opening ceremony. Old engravings and personal letters are also used to explain the relationship between Goethe and Charlotte von Stein.
