3. Kanaljorden, Sweden

In the quiet depths of a former Swedish lake, archaeologists uncovered a terrifying mystery; human skulls pierced on wooden stakes and arranged with ghostly care. Some bore signs of brutal trauma, as if their stories ended in violence before becoming part of a chilling ritual.
At Kanaljorden, the dead were not just buried; they were displayed, challenging everything we thought we knew about prehistoric hunter-gatherers and their relationship with death.
