Abstract; The Ravne 3 tunnels were first discovered in 2018 and form part of the Ravne tunnels complex. This prehistoric subterranean network of passages is located on the outskirts of Visoko City and is approximately 2.5km northwest of the Bosnian Pyramid of the Sun. At a point in the past, the tunnels had been backfilled with loose geological rubble. Work since 2006 has been undertaken to remove this material in order to further explore the underground passages. One of the dominating features identified across the Ravne tunnels complex is the employment of simple drystone walls, which act as retaining gravity walls, holding in place the loose backfill. The discovered drystone walls in Ravne 3 matched the form and function of those found elsewhere across the Ravne complex, indicating the Ravne 3 blockage must be contemporary with the rest of the tunnel network. One drystone wall within Ravne 3 was found stratigraphically below two stalagmites. Using the U-Th method, geochronological analysis derived a relative upper age limit on the construction of the drywall and tunnel backfill to the Upper Palaeolithic.

This curious geological formation is located a few kilometres down a track off the Sarajevo–Miljevina–Foča highway. Not so much ‘pyramids’ as they are pinnacles, these conical towers are produced by the natural processes of erosion.

World’s best tennis player Novak Dokovic visited the “Archaeological Park: Bosnian Pyramid of the Sun” on July 15th this year, and was hosted by the first man of this complex, Semir Osmanagic. In the interview with Sarajevo Times, Mr. Osmanagic said that they have spent three days together and that he showed him archaeological trenches in the Northern side of the Bosnian Pyramid of the Sun with the oldest and best quality concrete blocks, paved terraces on the western slope of the Bosnian Pyramid of the Moon, about 900 meters of the Prehistorical Underground Labyrinth Ravne, Foundation’s Museum with artifacts, satellite photos, lab analysis and radiocarbon dating results, newly discovered ‘Ravne 3’ tunnels with adjoining artifact exhibition, Air Spa, Healing Forest and Foundation’s Wellness Center and complete park ‘Ravne 2’ with its artistic, megalithic, botanical and recreational features.
