The Bosnian pyramids are a cluster of natural geological formations known as flatirons near the Bosnian town of Visoko, northwest of Sarajevo. The hill named Visočica became the focus of international attention in October 2005 following a news-media campaign promoting the idea that they are human-made and the largest ancient pyramids on Earth.
In analysing the site, its known history, and the excavations; geologists, archeologists, and other scientists have concluded that they are natural formations and that there are no signs of human building involved. Additionally, scientists have criticised the Bosnian authorities for supporting the pyramid claim saying: "This scheme is a cruel hoax on an unsuspecting public and has no place in the world of genuine science." A 2007 report suggests that one of the pyramids is a hill which has been modified into a pyramid-like shape by humans, possibly in order to prevent erosion, which is widely occurring in the area in question. A 2008 report calls for further research.
The 213-metre (699 ft) Visočica hill is where the Old town of Visoki was once sited. The idea that it constitutes an ancient artificial edifice was publicised by Bosnian author Semir Osmanagić. His subsequent excavations at the site have uncovered what he claims to be a paved entrance plateau and tunnels, as well as stone blocks and ancient mortar which he has suggested once covered the structure. Osmanagić has claimed that the dig involved an international team of archaeologists from Australia, Austria, Ireland, United Kingdom and Slovenia. However, many archaeologists he named have stated they had not agreed to participate and were never at the site. The dig began in April 2006, and has resulted in reshaping the hill, making it look like a Mayan step pyramid.
Osmanagić's interpretation 
Osmanagić has named the Visočica hill the "Pyramid of the Sun", and two nearby hills, identified from satellite and aerial photography, the "Pyramid of the Moon" (Plješevica hill) and the "Pyramid of the (Bosnian) Dragon" (another two, "Pyramid of the Earth" and "Pyramid of Love" have been mentioned in reports). Newspaper reports have quoted Osmanagić as claiming that they were constructed by ancient Illyrian inhabitants of the Balkans as early as 12,000 BC. In an interview with Philip Coppens in Nexus (April–May 2006), Osmanagić attempted to clarify his previous statements, stating he was misquoted: he does claim that they were most likely constructed by the Illyrians, who he claims lived in the area from 12,000 BC to 500 BC, and that the pyramid was therefore most likely constructed between those two dates – not in 12,000 BC.
Osmanagić claims the excavation has produced evidence of building blocks as well as tunnels. Additionally Osmanagić claims to have found tunnels in the hillside which he interprets as ventilation shafts.
Osmanagić believes his discoveries around Visoko will have further implications for world prehistory. By comparing the varying heights of the tallest pyramids in Mexico and Egypt with Visočica hill, he concluded that the pyramids were all built by the same people, with the Bosnian Pyramid being the last to be built. However, upon further thought he has decided that this dating mechanism may not be reliable and has now announced Visočica hill could be "The mother of all Pyramids", a claim he says would be corroborated by the existence of sacred geometry and further numerological study of messages left in the pyramid for future generations.
Osmanagić estimates that the Sun pyramid stands 722 feet (220 m) high (or, depending upon the report, either 230 feet (70 m) high or 328 feet (100 m) high). If it is 722 feet, it would be one third taller than the Great Pyramid of Giza, making it the largest pyramidal structure on Earth.
The current target of the project is to complete excavation by 2012. This is in order to "break a cloud of negative energy, allowing the Earth to receive cosmic energy from the centre of the galaxy" according to Osmanagić, who also hopes that it will be listed as UNESCO World Heritage Site.
In October 2011 a Sarajevo court ended a four-year court case by giving permission for further investigation of Visočica hill.
Scientific explanations 
Boston University's Curtis Runnels, an expert in prehistoric Greece and the Balkans states that, "Between 27,000 and 12,000 years ago, the Balkans were locked in the last Glacial maximum, a period of very cold and dry climate with glaciers in some of the mountain ranges. The only occupants were Upper Paleolithic hunters and gatherers who left behind open-air camp sites and traces of occupation in caves. These remains consist of simple stone tools, hearths, and remains of animals and plants that were consumed for food. These people did not have the tools or skills to engage in the construction of monumental architecture."
In a letter to the editor of The Times on 25 April 2006, Professor Anthony Harding, president of the European Association of Archaeologists, referred to Osmanagić's theories as "wacky" and "absurd" and expressed concern that insufficient safeguards were in place to protect Bosnia's "rich heritage" from "looting and unmonitored or unauthorised development". After visiting the site himself, Harding reported, "we saw areas of natural stone (a breccia), with fissures and cracks; but no sign of anything that looked like archaeology."
On 8 May 2006, members of the Geological team investigating Visočica on behalf of the Archaeological Park: Bosnian Pyramid of the Sun Foundation held a press conference in Tuzla to present the results of their research. The academics, from the Faculty of Mining and Geology at the University of Tuzla and led by Professor Dr. Sejfudin Vrabac, concluded that the hill is a natural geological formation, made of clastic sediments of layered composition and varying thickness, and that its shape is a consequence of endodynamical and exodynamical processes in the post-Miocene era.
According to Professor Vrabac, who specializes in paleogeology, there are dozens of similar morphological formations in the Sarajevo-Zenica mining basin alone. The Geological team report on Visocica, based on the data collected in six drill holes at 3 to 17 metre depths, is supported by the Research and Teaching Council of the Faculty of Mining and Geology, as well as the Association of Geologists of Federation of Bosnia and Herzegovina.
In June 2006, Zahi Hawass's name became linked to the excavations as recommending a supposed expert, Ali Abdullah Barakat, to investigate the hills. Barakat is affilated to the Egyptian Mineral Resources Agency, and has co-authored an article in the prestiguous scientific journal Science. Upon being contacted Hawass denied any involvement, accusing Osmanagić of "giving out false information", and clarifying that Barakat "knows nothing about Egyptian pyramids".
The Archaeological Park: Bosnian Pyramid of the Sun Foundation has said that Barakat inspected the hills and stated, "My opinion is that this is a type of pyramid, probably a primitive pyramid." In November 2007 an English version of a 2006 report by Barakat was posted on the foundation site. In the report, Barakat states that Visoko is located at an important intersection of ancient roads; that the age of the tunnel might be dated from karstification features;
On the Sun pyramid, Barakat writes, "The possibility that natural processes created this shape is very weak. Natural processes can create hazards, but not such pyramidal forms as these. (...) One may conclude that the human hands modified this hill to give it a more regular/geometrical shape (artificial pyramid) (...) The nature of this pyramid indicates that human hands sculptured the body of the pyramid from top to bottom. (...) This model of construction can be easily destroyed by natural processes, leaving the natural hill, thus only the traces of the covering stones may remain". Barakat suggests that reason for the sculpting of this pyramid may have been to protect it from natural processes, as the pyramidal form is a more resistant shape. His conlusion is as follows:
The observed hills (Visocica, Pljesevica, Buci) are most likely natural hills that were later modified in places by human activities, possibly during several historical episodes. The traces of such modifications have been either overprinted by later cultures, or by simple erosive tectonic processes, which are rather significant and far-reaching in a complex of the geographical, cultural and geological system, as seen in Bosnia and Herzegovina. Even though, there is a compelling evidence of the existence of the pyramid-shaped, man-made hill-forms in Bosnia, the results are still inconclusive and require further detailed geological, geophysical, tectonic and most importantly, archaeological studies.
Osmanagić also invited geologist and alternative archaeologist Robert Schoch to visit the site. In a preliminary report Schoch concluded that there were natural geological explanations for all the features claimed to be artificial by Osmanagić. In the case of the tunnels he further added:"The much-touted “ancient inscriptions” seem not to be ancient at all. I was told by a reliable source that the inscriptions were not there when members of the “pyramid team” initially entered the tunnels less than two years ago. The “ancient inscriptions” had been added since, perhaps non-maliciously, or perhaps as a downright hoax. Schoch's website documents "extreme damage being done by the way the excavations are being performed," and accuses Osmanagić of launching "a deliberate smear campaign."
In 2007 a report by Egyptologist Nabil Mohamed Abdel Swelim was publicised by the Archaeological Park which said that the Pyramid of the Sun was the world's largest pyramid. After two visits to Visoko he released a report in 2007 in which he concluded: “Arguments in favour or in disfavour have no effect on the fact that the pyramid concept and the properties are there for everyone to see”. However, in 2010 he released a report in which he clarified that he does not claim it is a man-made pyramid, but rather that he uses the term for any feature, natural or artificial, which is a geometric pyramid. He does not exclude the possibility it is man-made.
Osmanagić's claims, widely reported in the mass media, have been categorically refuted by a number of experts, who have accused him of promoting pseudo-scientific notions and damaging archaeological sites with his excavations. Amar Karapus, a curator at the National Museum of Bosnia and Herzegovina in Sarajevo, said "When I first read about the pyramids I thought it was a very funny joke. I just couldn't believe that anyone in the world could believe this." Penn State University Professor Garrett Fagan is quoted as saying "They should not be allowed to destroy genuine sites in the pursuit of these delusions[...] It’s as if someone were given permission to bulldoze Stonehenge to find secret chambers of lost ancient wisdom underneath."
Enver Imamović of the University of Sarajevo, a former director of the National Museum of Sarajevo, concerned that the excavations will damage historic sites such as the medieval royal capital Visoki, said that the excavations would "irreversibly destroy a national treasure". Excavations by archaeologists not related to the Foundation in the summer of 2008 uncovered medieval artefacts and led to renewed calls for the government to cancel Osmanagić's digging permits.
In response to the controversy, in his 2008 report, Nabil Swelim states, 
The realization of the presence of the Bosnian pyramid hills have generated joy, anger and other reactions that range from reasonable to temperamental. The angry and temperamental who claim that there are no pyramids in Bosnia must know that in scientific research: negative evidence is no evidence.
