The Erdmannlistein, glacial erratics in the Canton of Aargau, Switzerland. During the Würm glaciation the Reuss glacier transported these granite blocks from the Aarmassif northwards close to their current location. Most likely, humans then erected the blocks in neolithic times to be used as astronomic calendar or place of worship.
