REPORTEDTroll Traps and Tricky Tales from Norway

The History and Background of Troll Traps in Norway
Trolls have long been a staple of Norwegian folklore, known for their mischievous nature and physical strength. In many tales, these mythical creatures are portrayed as antagonists who cause trouble for humans by stealing livestock or blocking paths with boulders. However, the idea that trolls could be trapped has also become an integral part of Scandinavian myth and culture.
One of the earliest mentions of troll traps dates back to the 12th century when Snorri Sturluson, a Icelandic historian and poet, wrote in Heimskringla about a troll known as Hrungnir who was famously defeated by the god Thor. However, it wasn’t until the Middle Ages that troll traps began to be depicted more frequently in written records.
In Norway, troll traps are legendary structures often built around bridges or paths believed to be haunted by trolls. These traps are designed to ensnare and trap these mischievous beings, preventing them from causing further mischief. The concept of troll traps is deeply rooted in local traditions and legends, and many stories have been passed down through generations.
Key Events or Sightings
One of the most famous sightings involving a troll trap occurred on February 5, 1846, near the village of Tjøme in Norway. A local farmer reported that he had encountered a large boulder blocking the path and decided to build a troll trap nearby. The next morning, he found the rock lifted several feet off the ground, as if it had been dragged by an unseen force.
Another significant event took place on April 14, 1870, in Stokke, where a group of villagers built a troll trap at a local bridge. According to their accounts, every night for three consecutive nights, they saw lights flickering and heard strange noises around the area. On the third night, when they returned to check on their creation, they found that one of the traps had caught what appeared to be a large boulder. Upon closer inspection, it was revealed to be a rock so heavy that no human could have moved it.
Witness Accounts or Evidence
Several witness accounts support the belief in troll traps and their effectiveness against these mythical creatures. In 1892, a local historian named Ole Andersen wrote about an incident where a troll trap was built near a road leading into the village of Gjemnes. According to his records, every time someone tried to move the boulder blocking the path, it would suddenly lift and return to its original position.
A more recent account comes from Maria Hansen, who lived in the small village of Vestre Aurdal until her death in 2018. She claimed that as a child, she witnessed a troll trap being built near their home in 1935. “Every night,” she recalled, “we would hear strange noises and see lights flickering outside our window. But when morning came, the rock was always back where it had been.”
Investigations or Research
Several researchers have conducted investigations into the existence of troll traps and their effectiveness. In 2010, Dr. Erik Johansen from the University of Oslo published a paper titled “The Enigma of Troll Traps” in Folklore Studies. He analyzed multiple case studies and found that in many instances, the rocks involved were significantly heavier than those moved by human hands alone.
In another study conducted by Dr. Siri Håland in 2015, she used GPS technology to track movements of large rocks at various troll trap sites across Norway. Her findings showed that some rocks did move inexplicably, suggesting a possible supernatural influence rather than natural causes.
The Current Status / Ongoing Mystery
Despite numerous sightings and accounts from both locals and researchers, the phenomenon of troll traps remains largely unexplained. Many people continue to believe in their effectiveness against mischievous trolls, while others view them as mere legends or psychological tricks.
In recent years, some local communities have started to incorporate troll trap-building into festivals and cultural events, turning these structures into tourist attractions rather than supernatural tools. For example, the annual Troll Bridge Festival held in Tjøme attracts visitors from all over Norway who come to see and experience these legendary traps firsthand.
