Semir Sam Osmanagich is Bosnian-born Houston (USA) resident author, researcher and businessman. He discovered an ancient pyramid complex in Visoko, Bosnia-Herzegovina consisting, to date, of ten artificial structures: the Bosnian Pyramid of the Sun, the Bosnian Pyramid of the Moon, the Bosnian Pyramid of Love, the Bosnian Pyramid of the Dragon, the Temple of Mother Earth, Vratnica Tumulus, Dolovi Tumulus, Ginje Tumulus, KTK Tunnel, and Ravne Tunnel Labyrinth.
Semir Osmanagić (born 1 June 1960 in Zenica, SFR Yugoslavia), also known as Sam Osmanagich, is best known for promoting the pseudo-archaeological projects related to the ‘Bosnian pyramid‘. Osmanagić claims that a cluster of natural hills in central Bosnia and Herzegovina are the largest human-made ancient pyramids on Earth. Professional geologists, archeologists and other scientists have concluded – after analysis of the site, its known history, and excavations – that the hills are natural formations known as flatirons and that there are no signs of human construction involved.
