Considering the Hotel Augusta in Augsburg?
A VT member wrote the following comment about visiting Augsburg:
Where the Fuggers lived and reigned by King_Golo
The Fugger Houses in the centre of Augsburg once were the family's trade empire headquarters. From here, they dominated the European trade. Today, the buildings are an exclusive address and house an expensive restaurant, some companies and the Fugger Private Bank. You can walk across the yards in the middle of the buildings, but I'm not sure if there's a guided tour through the buildings themselves.
