Magic of the Devil's Church: A Shaman's Sanctuary in Finland
Written on
Chapter 1: Enigmatic Origins of the Devil's Church
In the heart of Koli National Park, eastern Finland, lies a renowned crevice cave measuring 34 meters in length, known locally as Pirunkirkko or the Devil's Church. This site has long been a focal point for shamans and other spiritual practitioners who believe it serves as a gateway to the spirit world.
Cave tourism thrives in this area, with visitors drawn not only to its natural beauty but also to its spiritual allure.
Section 1.1: The Acoustic Mystery of the Cave
Researchers Riitta Rainio from the University of Helsinki and Elina Hytönen-Ng from the University of Eastern Finland embarked on a study to understand the acoustics within this cave. Their investigation sought to uncover the unique sound phenomena that have captivated people for centuries.
They discovered that the Devil’s Church demonstrates a resonance effect that amplifies and extends sound at a particular frequency. This finding may have profound implications for the experiences and beliefs of those who enter the cave.
Section 1.2: Tales of Shamans and Healing
An extensive review of historical documents revealed that several healers operated in the vicinity of the current Koli National Park. The most notable was Kinolainen, also known as Tossavainen, who famously employed the Devil’s Church for his healing ceremonies.
“Local folklore suggests that Kinolainen would guide his patients into the cave to engage in discussions with the devil regarding the origins and remedies for their ailments. These healing sessions frequently involved loud vocalizations, stomping, and other vigorous actions,” Rainio recounted.
Chapter 2: Scientific Insights into the Cave's Acoustics
The researchers conducted detailed acoustic measurements within the cave, particularly in its farthest reaches, where they found a significant resonance effect. The cave's walls create a corridor-like environment that produces a standing wave, resonating at a natural frequency of 231 Hz.
This frequency remains audible for approximately one second after any loud sound, such as clapping or drumming.
“We recorded a shaman in practice and found he repeatedly generated sounds at the frequency of 231 Hz, which the cave amplified due to its natural resonance,” Rainio elaborated.

Resonance in Nature: Uncommon Yet Significant
The acoustic phenomena observed in the Devil’s Church are more commonly found in modern spaces but are rare in natural environments like caves. The unique smooth and parallel surfaces within this cave contribute to its extraordinary resonance, which likely held great significance for the local population, fostering beliefs in its supernatural qualities.
Interestingly, similar acoustic effects have been documented in Paleolithic caves across France and Spain, particularly near ancient cave art. This suggests that early humans were attuned to acoustic properties, which may have influenced their choice of sacred sites.
As researchers noted, where modern scientists detect resonance, our ancestors may have felt the presence of spirits, and shamans could have sensed remarkable energies. Ultimately, these experiences are shaped by individual perspectives and cultural contexts.
