Nyköping Labyrinth is a prehistoric or medieval stone-formation labyrinth in Södermanland, Sweden. The design is a classical 11circuit layout with 11 circuits, 12 walls, built of stone. Documented age: 15th-16th century (15th-16th century). Current condition: restored. A stone labyrinth near the Baltic coast at Nyköping, south of Stockholm — a town whose medieval castle was the site of the infamous Nyköping Banquet of 1317, where King Birger imprisoned and starved his rival brothers. Documentation sources: Kraft 1983. A pattern with one entrance, one path, and no choices — repeated by unrelated cultures across thousands of years. 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.
