When Anna learned in December 1575 of her upcoming transferral to Saxony, she attempted suicide. After a long stay in Zeitz, she was taken to Dresden in December 1576. There, the windows of her room were walled up and fitted with additional iron bars. At the door was a square hole in the top panel that provided a narrow grid, which was closed off outside. Through this hole food and drinks were served to her. At the door there was also another iron gate, virtually guaranteeing no chance of escape.
