The Bosnian pyramid complex is a pseudoarchaeological notion to explain the formation of a cluster of natural hills in the area of Visoko in central Bosnia and Herzegovina. Since 2005, Semir Osmanagić, a Bosnian American businessman now based in Houston, Texas, has claimed that these hills are the largest human-made ancient pyramids on Earth. His claims have been overwhelmingly refuted by scientists but he has proceeded to promote the area as a tourist attraction. By June 2016, Osmanagić had completed an archeological park at one of the hills, where he attracts volunteers who are constructing botanical gardens; meditation sessions have been held at the site. It has been noted that tourist traffic has aided the economy of the city of Visoko, located near the front of the war that destroyed so much of the country in the late 20th century.
Direct study of the site by geologists, archaeologists, and other scientists have demonstrated that the hills are natural formations known as flatirons and that there is no evidence that they were shaped by human construction.
