Bolshoi Zayatsky Island’s stone labyrinths, Russia
The Solovetsky islands are decorated with a whimsical stone lace — the spiral shaped labyrinths. The locals called them ’Babylons.’ The entrance and the exit are the same. So if you go strictly on the tracks formed by the boulders, after a while you can exit where you entered. But what was it before? Some scholars write about practicality, like fish traps. The others write that they were meant for entertainment, as a playground for round dances and games. But the majority is pretty sure that these labyrinths were ritual structures on the border with the spirit world.
