On the way from the Duchess Anna Amalia Library to the market, I pass a Renaissance portal with a strikingly large number of coats of arms. The windows have colourful lines like fresh make-up. The gate belongs to the Red Castle (Rote Schloss), which was built in the years 1574/76 as a widow’s residence for Duchess Dorothea Susanne.
A closer look at the central coat of arms reveals that it represents the alliance coat of arms between the Duchess and her husband. This one is Johann Wilhelm, Duke of Saxe-Weimar.
