Bunge Trojaborg is a prehistoric or medieval stone-formation labyrinth in Gotland Island, Sweden. The design is a classical 11circuit layout with 11 circuits, 12 walls, approximately 16 metres in diameter, built of stone. Documented age: 1970s construction (1970s construction). Current condition: intact. A 12-wall double-angle classical labyrinth built in the late 1970s west of Route 148, opposite Bunge Church and adjacent to the Bunge Museum — one of Gotland's premier open-air heritage sites. Documentation sources: Gotland Trojaborgs PDF. The same seven-circuit topology appears at this site as at every other classical labyrinth on Earth. 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.
