But there is another tradition, which seems to be at least 200 years old, which I will let wikipedia explain:
There were once many hundreds, perhaps even thousands, of these labyrinths around the Baltic Sea, throughout Fennoscandia and the Baltic countries, and many of them still survive, particularly in remote areas. There are also similar stone labyrinths in the Kola Peninsula and coasts and islands of the White Sea, such as Stone labyrinths of Bolshoi Zayatsky Island. For some reason these northern labyrinths are almost all close to the sea. Some have suggested that they were markings of seafarers, perhaps even used for navigation. Many of the stone labyrinths around the Baltic coast of Sweden were built by fishermen during rough weather and were believed to entrap evil spirits, the "smågubbar" or "little people" who brought bad luck. The fishermen would walk to the centre of the labyrinth, enticing the spirits to follow them, and then run out and put to sea.
So these are a fun distraction, a bit of modern mystery with very ancient mystical associations.
