Bosnian Pyramid of the Sun and Ravne Tunnels

Semir Osmanagić announced in 2005 that the hill above Visoko is a pyramid tens of thousands of years old, and started digging the following April. In December 2006, the European Association of Archaeologists published an open letter calling the project a cruel hoax with no place in genuine science. The digging did not stop, the tunnels are ticketed, and the town gets the visitors.

Field Guide Entry

The claim

Visočica is a steep hill with straight-looking faces above the town of Visoko. Osmanagić, a Bosnian American businessman and author, said in 2005 that those faces are the sides of a buried pyramid, that it is older than anything in Egypt, and that a complex of other pyramids and tunnels surrounds it. Excavation began in April 2006 with volunteers, a foundation, and a great deal of press.

What geologists say it is

Geologists who examined the hill reported a natural landform. The shape is a flatiron, produced where tilted layers of hard rock erode into triangular faces, and the slabs presented as paving are the layered breccia and conglomerate the hill is made of. The 2006 open letter from the European Association of Archaeologists went further than a technical disagreement and asked the Bosnian government to stop supporting the work, on the grounds that it was damaging real archaeology in the area.

Visoko does hold genuine archaeology. The medieval town of Visoki sat on the same hill, and that site was disturbed by the pyramid excavations, which is what the archaeologists were protesting about.

The tunnels

Ravne is a network of passages near the hill, cleaned out, widened, and timbered by the foundation and sold as the tunnels of the pyramid complex. Visitors are told about energy beams measured at the summit, air that heals, and water with unusual properties. None of that has been demonstrated in any published work.

What it did to the town

Visoko had lost its industry. The pyramid brought guesthouses, guides, cafes, and a summer volunteer program, and it is one of the few places in the region where tourism arrived rather than left. Reporters who go there, including Radio Free Europe, tend to come back with the same finding: the archaeology is not in dispute among archaeologists, and the money is real.

Visiting Information

The Ravne tunnels are entered only with a guide. First entry is at 9am and the last is at 6pm, and tickets are 20 convertible marks, or 8 for citizens of Bosnia and Herzegovina. Helmets are issued at the entrance, the floor is uneven and wet in places, and the air inside stays cool whatever the season.

The hill itself is open, with a marked trail up through the excavated terraces to the summit, and it takes a couple of hours at an ordinary pace. The terraces are trenches cut into the slope, and the interpretation boards beside them present the pyramid account as settled.

Day tours from Sarajevo run through the year and bundle transport with tunnel entry. Visoko is a short drive from the city, and the old town is worth the walk once the tunnels are done.

Actun Tunichil Muknal

Cayo District, Belize

Fourteen sets of human remains lie in the upper chamber where they were left more than a thousand years ago, some of them children. Pots sit among them with holes punched through the base so nobody could use them again. Cameras have been banned since 2012, when a visitor dropped one onto a skull.

Ale's Stones

Skåne County, Sweden

Fifty-nine boulders stand in the outline of a ship on a ridge above the Baltic, the largest weighing about five metric tons, hauled up a slope to a spot with no shelter and no water. Radiocarbon evidence places the monument broadly in the later Iron Age, around 500 to 1000 CE. An amateur astronomer has spent decades arguing it is thousands of years older and is a solar calendar, and no working archaeologist accepts it.

America's Stonehenge

New Hampshire, United States

A hillside maze of stone chambers, walls, and a grooved "sacrificial table" in New Hampshire has been called both a 4,000-year-old ceremonial site and a 19th-century farmer's root cellars. A century of argument has not settled it.

Antikythera Mechanism

Attica, Greece

Sponge divers raised this corroded bronze device from a shipwreck off Antikythera in 1901. X-ray scans in 2005 showed it was a geared calculator that predicted eclipses, tracked the moon and a cycle of athletic games, and, by its own inscriptions, displayed the five planets then known. Who built it, where, and when are still argued over, and no known device matches its complexity for at least a millennium afterward.
