In connection with the persecution of Jews in Mecklenburg, the Wismar Jewish pogrom of 1270 was followed by the alleged host desecration in 1325 in Krakow am See, which has been cited in numerous publications, although the specific details of this incident have not survived.
According to the few surviving details, events unfolded as follows: In 1325, Duke Johann II, known as "the Bald" and Lord of Werle-Guestrow, confiscated all the property of the Jews on the basis of accusations against them that they had broken open the church door, stolen hosts, subsequently pierced them, and trampled the fragments into the street dirt, and had the convicted Jews broken on the wheel on the local Joernberg despite their protestations of innocence. From their confiscated belongings, a chapel, the Holy Cross Chapel, was eventually erected, in which the remains of the tortured hosts were preserved.
