We walked those cobblestone streets to two overlooks. If you look closely or click on this photo you can see our ship on the upper right.
I'll show you that crazy chicken weathervane later. This is a tower that seperated the upper city of the nobility from the lower city of the merchants made rich by the Hannseatic League. The nobility had some advantages over the merchants, but ultimately the merchants could close off the gates of this tower that link the upper town with the lower town and wait the nobility out. The found ways to get along. I suspect that the other power of the merchants were their goods. How noble can you be without noble things around you and particularly noble things to eat.
This is not taken from the overlook, but is the tower from lower town.
