This is the courtyard to the Altes Schloss (Old Castle) and part of the Württemberg Museum. Sit at the museum's Schlosscafé to the left and get immersed in Renaissance architecture. Some workers at the bottom left were making repairs to the exterior.
Entrance to the Württemberg Museum, but I did not have time to go inside.
Statue of Eberhard I, Duke of Württemberg from the 1400's. He was also known as "Eberhard im Bart" (Eberhard the Bearded)
