The "Great Stone of Tonnenheide" is 10 meters long, 7 meters wide, and 3 meters high. It weighs approximately 350 tons. It is the largest known erratic boulder in Northern Germany.
The stone material of this boulder is approximately one billion years old. It is composed of biotite granite. The block most likely originates from the southern Swedish province of Blekinge, an area approximately 750 km from the current site. Around the turn of the century, geologist Professor Dr. Wegener examined the boulder and determined its dimensions to be 7 meters long and 5 meters wide.
