Goslar is a lovely town in central Germany and is home to the Imperial Palace of Goslar XI century. From outside it is not much to look at but inside it has an incredible throne room, 7m high, which is decorated with huge paintings explaining the history of kings, German emperors and legends, battles and other historical moments, all with great quality and exceptional detail. I couldn't take pictures in the throne room as it was forbidden and the guards did not allow it, but the quality of the paintings and the detail was exceptional. For me it is the German "Sistine Chapel". Interestingly, the painter took 18 years to finish it. Also, if you take one of the tours that they do for free, as well as explaining the history of the paintings, they will show you incredible details, like a lady pointing a finger at both directions of the room depending on where you look, or an horse who is alway watching you wherever you are. Simply amazing. The admission charge is about 5€, although there are discounts for students and young people.
