After a fire in the town palace, Wittumspalais was turned into the dowager residence of Duchess Anna Amalia. The two-winged building is an important document of noble interior design in Weimar.
Luminaries of Classical Weimar used to meet up in the "Round Table Room" to talk and exchange opinions, while the "Friday Society" set up by Goethe also met for a while at Wittumspalais. Following the death of the Duchess, the building was no longer permanently inhabited, and was instead used as a guest-house and meeting place by the Amalia Masonic Lodge.
The Wittumspalais is part of the ensemble "Classical Weimar", that was declared a UNESCO World Heritage in 1998.
