Spikstenen

Spikstenen is a large glacial erratic boulder situated within a protected natural area in Södermanland County. The stone reveals how ancient ice sheets moved massive rocks across the landscape during the last ice age.

Spikstenen received official protection as a natural monument in 1924, marking an early milestone in Sweden's efforts to preserve geological formations. This conservation measure reflected a growing recognition of the scientific and natural value of landscape features.

The Södermanland County Administrative Board maintains this natural site, which represents Sweden's dedication to preserving geological formations for future generations.

The site is accessible on foot and easy to locate with GPS coordinates or a map. Visitors should come prepared for variable weather and wear sturdy footwear, as the surrounding terrain can be overgrown and sometimes marshy.

The boulder belongs to a group of stones carried by ice masses from Norway during the last ice age. Such erratics serve as important clues for geologists to understand the direction and force of ancient glacial movement.
