Pyramid in Bosnia may be one-third taller than Egypt’s Great Pyramid of Giza

Bosnia-Herzegovina - Researchers in Bosnia on Wednesday unearthed the first solid evidence that an ancient pyramid lies hidden beneath a massive hill ? a series of geometrically cut stone slabs that could form part of the structure's sloping surface.

Archaeologists and other experts began digging into the sides of the mysterious hill near the central Bosnian town of Visoko last week. On Wednesday, the digging revealed large stone blocks on one side that the leader of the team believes are the outer layer of the pyramid.

"These are the first uncovered walls of the pyramid," said Semir Osmanagic, a Bosnian archaeologist who studied the pyramids of Latin America for 15 years. - msnbc
