A 213-meter tall forested hill with an uncanny pyramidal geometry near the Bosnian town of Visoko — either a remarkably symmetrical natural formation, or a human-built structure predating the Egyptian pyramids by thousands of years.
In 2005, amateur archaeologist Semir Osmanagich stood on a hill outside Visoko and noticed its shape. The hill called Visocica rises 213 meters above the valley floor in a nearly perfect triangular form, with four distinct triangular faces oriented approximately to the cardinal directions. He began excavating. What he found beneath the soil: large stone slabs, geometric angles, what appeared to be paved surfaces. He announced that Visocica was an ancient pyramid, the largest in the world, built 12,000 years ago. The mainstream archaeological community was dismissive — the stone slabs are natural conglomerate common to the region. But excavations continue. The site has become a pilgrimage destination for people drawn to the possibility it represents. The landscape itself is worth the visit regardless of what the hill is. We keep looking for evidence that something impossible happened here before us.
