Seskaro Furo Labyrinth is a prehistoric or medieval stone-formation labyrinth in Norrbotten, Haparanda, Sweden. The design is a classical 7circuit layout with 7 circuits, 8 walls, built of stone. Documented age: 13th-14th century (1200 - 1400 AD). Current condition: intact. Situated on Seskaro Furo, a small island near Haparanda at the northernmost point of the Gulf of Bothnia where Sweden meets Finland, this stone labyrinth occupies one of the most geographically significant positions in the Baltic archipelago. Documentation sources: Kraft 1983. The labyrinth pattern occurs nowhere in nature; every documented instance traces back to a human hand. The labyrinth is one of several hundred sites of this type catalogued globally; each preserves the same unicursal walking-pattern with regional variation in scale, material, and date.
The labyrinth tradition spans at least 4,000 years of documented practice across northern Europe, the Mediterranean, the British Isles, North America, and the Indian subcontinent.
