Seydozero is a lake in the Lovozero Massif on the Kola Peninsula (Murmansk region). "Seid" means "sacred" in Sami. The length of the Seidozero is 8 km, the width is from 1.5 to 2.5 km.
According to a number of science fiction writers and ufologists, one of the supposed places of existence of the Hyperborean civilization. Seekers of the unknown have been exploring these places since 1922; it was then that the expedition of Alexander Barchenko, a doctor, occultist, and OGPU employee, who was seriously interested in various mental phenomena, in particular, "menerik" or Arctic psychosis, cases of which were noted on the Kola Peninsula, went here. The expedition discovered a number of artifacts, on the basis of which Barchenko made a statement about the discovery of Hyperborea.
In 1938, Barchenko was shot as an enemy of the people, and the search for Hyperborea temporarily stopped. They were resumed in 1997 through the efforts of Valery Demin, Doctor of Philosophy, who organized a new expedition to the Seidozero "in the footsteps" of Barchenko. Some of the finds of the Barchenko expedition were never discovered, but new discoveries appeared. To study them in more detail and search for new artifacts, Demin organized new expeditions in 1998 and 2001 with the involvement of a large number of specialized equipment and various experts: from geophysicists and experienced divers to explore the bottom of the lake to psychics.
New searches stopped after Demin's death, and did not leave behind any significant scientific evidence about the existence of Hyperborea. But Seydozero has gained all-Russian and even world fame. Thousands of tourists come here every year, who consider it a "place of power" and want to look at the artifacts. Including the famous image of the mythical giant Kuiva, a rock with his image is located on the shore of the lake.
According to Sami legends, Kuiva lived in ancient times in the Lovozero Massif. The giant robbed and killed the Sami, for which he was destroyed by the Sami pagan gods — "burned by lightning that struck from the waters of the lake." After burning on the rock, the Seidozero left an imprint of his burned body, resembling a human silhouette. The height of the silhouette is 74 m.
