The "caffagium" (tax office) from the Middle Ages. Situated south of but not part of the cloister Mariencroon.
In 1455 a fund was founded for the poor. The caffagium came into posession of this foundation called "Armenpoth" in 1549 to extend it's distribution to the poor.
I turned into a little street and saw this very old nice house. I think the main living area must be on the 1st floor because the ground floor looks rather low.
