A site known as Visočica hill (or Grad hill), in the Bosnia-Herzegovina town of Visoko,

northwest of Sarajevo, became the focus of international attention in October 2005,

following a news-media campaign promoting the idea

that it is actually the largest of a group of ancient man-made pyramids,

the so-called Bosnian pyramids.

Scientific investigations of the site show there is no pyramid.

Additionally, scientists have criticised the Bosnian authorities for supporting the pyramid claim saying,

"This scheme is a cruel hoax on an unsuspecting public and has no place in the world of genuine science."

The 213 metre Visočica hill, upon which the Old town of Visoki was once sited,

is roughly pyramid-shaped. The idea that it constitutes an ancient artificial edifice was publicised

by Houston-based expatriate Bosnian author and metalworker Semir Osmanagić,

whose subsequent excavations at the site have uncovered

what he claims to be a paved entrance plateau and tunnels, as well as stone blocks

and ancient mortar which he has suggested once covered the structure.

Osmanagić has claimed that the dig involved

an international team of archaeologists from Australia, Austria, Bosnia, Scotland and Slovenia.

Conclusion :

On Pljesevica we didn't find a single archaeological artifact, and it is,

in my opinion, sterile in the archeological sense
