Bad Sassendorf in the federal state of North Rhine-Westphalia, Germany, is located roughly midway bewteen Dortmund or Hagen, and Paderborn. The prefix "Bad" indicates a spa town. Since the 10th century, Sassendorf is noted for its salt springs.

The workshop will be held on the premises of the (converted) farmstead Hof Haulle, with the former barn serving as our lecture hall. Another building now houses the museum Westfälische Salzwelten. Participants are invited to join us for the welcome reception on Thursday evening in the rooms of the museum.
