Visoko (Bosnia and Herzegovina) - The Bosnian hill Visočica near the Bosnian capital Sarajevo may indeed be an ancient pyramid. Scientists who have been examining the peak with remarkably regular shapes since last week have encountered the first blocks of allegedly worked stone. A somewhat clearer outline emerges for the vision of amateur archaeologist Semir Osmanagić, who sparked "pyramidomania" in Bosnia and Herzegovina and claims that the oldest European pyramid is located near the town of Visoko. Archaeologists have announced that they found regularly cut blocks on one of the slopes of the 650-meter-high mountain. According to Osmanagić, who leads the archaeological work, this is the upper layer of a massive step pyramid. "These are the first revealed walls of the pyramid," claims the enthusiast who studied pyramids in Latin America for 15 years. "We can see that the surface is perfectly smooth," he noted. Osmanagić is convinced that the hill was shaped by the Illyrians, who inhabited the Balkans long before the Slavic tribes conquered it around the year 600 AD. Beneath the layers of soil, experts have so far discovered, in addition to large stone blocks, a paved entrance platform and entrances to tunnels. The huge stone blocks reportedly look like smoothed cubes, and according to Osmanagić, it is clear that their surfaces were worked by humans. Osmanagić intends to continue the research until the summer, when, according to him, the pyramid should be visibly uncovered. Measurements have shown that Visočica has regular shapes, a flat top, and that its slopes with a 45-degree inclination are precisely oriented towards the individual cardinal directions. Satellite and infrared images have additionally revealed that there are two smaller pyramid-like hills in the same valley.
