Trondheim Labyrinth is a prehistoric or medieval stone-formation labyrinth in Trøndelag, Norway. The design is a classical 7circuit layout with 7 circuits, 8 walls, built of stone. Construction date is recorded as unknown in the surveyed catalogue. Current condition: restored. A stone labyrinth near Trondheim, associated with the medieval pilgrimage tradition to Nidaros Cathedral — the northernmost medieval cathedral in Europe and the burial site of St. Olav, Norway's patron saint. 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.
