We went there on Sunday, maybe not the best choice of a day for travelling to Germany, but I have to say that the surrounding void in the city was somehow charming. And we were lucky anyway, because there was a pottery sale / exhibition at the marketplace, which definitely generated some life around.
The pottery sold was really quaint and (I would even say) old-school and artistic. That is why I wouldn't call the venue a sale, for me it was more of an exhibition with the possibility to buy the exhibits.
When we were done watching the pottery, we went to explore the town. Since Greifswald is rather small, we just tramped along with no specific aim. I was really entranced with the surroundings (as I always am in Germany). Everything was so neat and nice, making me feel very peaceful.
Since Greifswald is situated at the bay, we took the chance to walk along the water. The weather was exceptionally good for September and I guess at the bay the mistery of abandoned Greifswald was solved. Everyone was at the promenade by the canal, many people were sailing. What a lovely way to spend sunny Sunday.
