Castle Kaiserhaus in Goslar

You're standing at the Imperial Palace of Goslar, at the foot of the Rammelsberg hill. That long Romanesque building in front of you is the Kaiserhaus, the heart of the whole complex. It's the largest and best-preserved secular building from the eleventh century in Germany, about fifty-four metres long and eighteen metres deep. Look at the row of windows on the upper floor. Behind them sat the emperor and his closest circle. Lesser courtiers made do with the hall downstairs.
