Brezeltante Anna Grieben Statue

In front of the town hall stands a sandstone relief depicting the historical figure of the Pretzel Aunt. It depicts Anna Grieben, who died in 1617. According to tradition, she is the founder of the "Pretzel Salve." In the 17th century, this wealthy woman came up with the idea of giving Lenzen students pretzels at the beginning of each school year. The tradition continued until the beginning of the last century. Since Lenzen's anniversary in 2004, the historical figure of the Pretzel Aunt has once again been omnipresent.

In Lenzen, the "Brezeltante" (pretzel aunt) has been resurrected after 400 years – she has always held a place in the stories of the residents and was a very special woman. Nowadays, she can not only be seen from time to time in historical costume, but can also be seen as a sculpture in front of the town hall.Source:
