History-laden hill contains human-made tunnels, researchers say
VISOKO, Bosnia-Herzegovina - Archaeologists began digging Friday for what they hope is an ancient pyramid (http://www.piramidasunca.ba/) hidden beneath a mysterious Bosnian hill that has long been the subject of legend.
The Bosnian archaeologist leading the work says the 2,120-foot (650-meter) mound rising above the small town of Visoko resembles pyramid sites in Latin America that he has studied. It would be the first pyramid ever discovered in Europe.
Initial research on the hill, known as Visocica, found that it has perfectly shaped, 45-degree slopes pointing toward the cardinal points and a flat top. Under layers of dirt, workers discovered a paved entrance plateau, entrances to tunnels and large stone blocks that might be part of a pyramid's outer surface.
