The Prenden Giant Stone

The glacier ice carried this boulder from Scandinavia to Northern Germany during the Ice Age

A legend is entwined around the imprints found on the stone. After that, a long time ago a giant (or the devil) threw a handful of stones on the bell tower of the village church, because it bothered him the beautiful, but loud bells. The church tower was not hit, two of the five thrown stones remained lying on the Strehlesee, three flew too far and their splashes from the Wandlitzer lake formed the three holy Pfühle. The stone bears the inscription "Kaiser Wilhelm II". The stone is a glacial relic and consists of Revsund granite. The geological investigation revealed as the place of origin today's Sweden.

If you come automatically past it when you circle the lake and signposted is the glacial boulder also.
