Are the oldest pyramids in central Bosnia? The evidence is compelling, writes Caroline Hurry

When local children showed  “Professor Sam” a cave near the home of Haris Delibasic in Visoko, 40km northwest of Sarajevo in 2006, little did Delibasic know how his personal paradigm would shift as he had been exploring the cave since childhood.

First, he learnt the hills framing his village were, in fact, four, vegetation-covered, 30 000-year-old pyramids, with an exact zero-degree north orientation. Then, the cave turned out to be the entrance to the “world’s most extensive underground network of tunnels”.

Professor “Sam” Semir Osmanagic, head of Bosnia-Herzegovina’s American University’s Anthropology Department and author of 15 books on ancient civilisations, discovered the Visoko pyramids in 2005 and knew the tunnels were there … somewhere.

“When children showed him the cave, he started excavations the next day and more tunnels emerged within 72 hours of clearing,” recalls Delibasic, senior guide at the dig, now in its 11th year.

Delibasic believes the tunnels could stretch for hundreds of kilometres.

“An advanced civilisation with technology far superior to anything we have today, built these tunnels within a single generation by hollowing out the post-glacial conglomerate for 3,8km in eight directions – linking the Sun, Moon, Love, and Dragon pyramids. After digging out the tunnels, they added pebbles, quartz crystal, and limestone to the excavated conglomerate to build the pyramids,” he says.

We are sitting in the Ravne tunnel network’s “healing chamber” 2,5 km from the Sun pyramid, which at 220 metres, is a third higher than Egypt’s Great Pyramid of Giza.

Indeed, the Visoko valley’s ancient name was Egipat, which means Egypt.

Earlier my husband and I had climbed the Sun pyramid, which affords a great view of Visoko below. The massive concrete blocks that cover all sides beneath the vegetation looked impressive. Independent analysis from five European universities confirms the material is five times stronger and more resistant to water than any man-made concrete today.

I’m feeling ever so rejuvenated thanks to all the negative ions generated by an egg-shaped 8 000kg monolith – one of three – found in the chamber. Analysis by the Institute for Nuclear Physics in Zagreb proved the 35 000-year-old quartz monolith covered in man-made ceramic, generates ultra-sound frequencies and magnetic energies. Varying ceiling heights further circulate the airflow throughout the network of tunnels.

Comments Delibasic: “No way were pyramids used as burial places. The ancients, who knew the secrets of frequency, used pyramid energy to advance human health, so it can’t ever have been a place for dead people.”

Says Delibasic: “This would have made it the Earth’s biggest antenna but the tunnels were filled in with soft sand around 4 600 years ago, effectively putting the pyramid on “standby” with just 3% of its capacity. Perhaps this was to prevent the technology falling into the wrong hands.”

Mainstream scientists can scoff if they like. The Bosnian government intends to keep digging.
