Gotland Stone Labyrinths (Cluster)

The Baltic island of Gotland, Sweden, hosts over 40 stone labyrinths — the highest concentration on any single island in the world. These range from ancient (Bronze Age) to medieval to modern reconstructions, creating a continuous 3,000-year labyrinth tradition on one landmass. Gotland's position in the center of the Baltic Sea made it a crucial Viking-era trading hub, and the labyrinths are concentrated along coastlines — suggesting navigational or maritime ritual functions. Local tradition called them "Trojeborg" (Troy Town), connecting them to Mediterranean labyrinth mythology. Researcher Erwin Reissmann's documentation revealed that many align to significant astronomical directions.
