Das PolenmARkT Festival

In the organizer's words:

Every year in November, the city of Greifswald and numerous towns in the Vorpommern-Greifswald district are transformed into an energetic meeting place for Polish art and culture. The festival, whose origins go back to a frugal student evening that wanted nothing more than to bring Poland closer, has since become one of the most important cultural events in north-eastern Germany and the largest festival of Polish culture abroad.
