Hohenstaufen, empires, Holy Roman Empire
Those who visit Goslar, jewel of the Salian and Hohenstaufen emperors, will be introduced to one of the most beautiful and best preserved romanesque Pfalzen, which served the medieval emperors as regional residences. The stately throne hall received its present decor in the years 1879-97, when Herman Wislicenus created a series of huge murals depicting great events in the history of the Holy Roman Empire. The most romantic and prophetic of these paintings portrays Frederick Barbarossa. It is a visual expression of a popular medieval legend that envisioned the return of Kaiser Rotbart.
