Is Bosnia home to Europe 's first pyramids?

Osmanagic first noticed the irregularly shaped hills when he visited Visoko in April 2005 to research its medieval legacy. The town was Bosnia 's capital during the middle ages, and a medieval fortress used by Bosnian kings sits atop one of the hills, Visocica. The fortress was built over an old Roman Empire observation post, which in turn was constructed over the ruins of an ancient settlement.

Preliminary digging uncovered mysterious slabs in a stone not native to the immediate area. Further excavations started in April 2006 and satellite images, thermal analysis and radar studies have been performed at the site, all independently confirming the existence of pyramid-shaped architecture according to Osmanagic who has spent fifteen years studying pyramids throughout the world and much of that time was in Mexico and Central America.

Osmanagic named the hills as the Bosnian Pyramid of the Sun and the Bosnian Pyramid of the Moon. Subsequent measurements revealed the height of the Sun pyramid to be 220m and the Moon pyramid at 190m, both higher than Egypt 's Great Pyramid which stands at 147m. Both hills have all the elements of a pyramid, including four perfectly-shaped slopes pointing toward the cardinal points, a flat top and an entrance.

Later, by using satellite imaging, Osmanagic discovered three more pyramid-like structures, and named them the Bosnian Pyramid of the Dragon, Mother Earth and Love. The whole site was called the Bosnian Valley of the Pyramids.

Despite the tests and pictures, some archaeologists aren't convinced by his claims.

Since the site was discovered, visitors have flocked to Visoko, with more than 200,000 visiting the area last summer. Locals have begun to trade on the excitement, selling pyramid-themed souvenirs to tourists and visitors, and restaurants serving meals in a triangle shaped plates.
