Stone labyrinths of Bolshoi Zayatsky Island

Lacking standard archaeological study, a research group from St. Petersberg theorize that the labyrinths are about 2500 years old, according to their orientation, their supposed ritual use, and changes in the direction of the zenith on the solstice throughout history.

[1] Most researchers doubt that they are that old; the vast majority of labyrinths in this area date at the earliest to the Middle Ages.

Another enormous complex of stone settings on Sopka Hill, in the eastern part of the island, does not include any labyrinths.

The entrances are generally on the southern sides of the labyrinths, but can also be found in the south-western, eastern or western parts.

Another hypothesis is that the settings may have served as a model for complex fishing equipment.
