A US-based Bosnian independent researcher, Semir Osmanagic claims in his new published book "The Bosnian Sun Pyramid" that a 700 meters high hill near Sarajevo was actually the oldest known pyramid of the world. According to Osmanagic, archaeological researches has already revealed some sandstone slabs 5 meters below the surface. He recalls the German archaeologists' latest findings of 7000 years old artifacts near the hill. He claims that the "Bosnian Pyramid" dated back 12 thousand years and had same characteristics of the famous Step Pyramid of Saccara. Another Bosnian scientist, Nada Nukic (a geologist) supported his claims by stating that the structure of the hill could hide some "man made" buildings.
