The Kannestein was formed by loose rock and the ebb and flow of the waves. The stone is cup-shaped and measures 4-5 meters in height. For centuries, pebbles rubbed against the rock until they were rounded. These loose stones have carved the rock deeper and deeper over time. More and more stones were added, and so gradually larger and wider hollows could form.
Several depressions formed next to each other, which were ground out until the side walls disappeared and only the middle part remained. This is how the interesting shape of the Kannestein came about. Because of this process, he will one day abort Kannestein.
