Archaeologists who dig near Prague discovered the remains of a stone age structure older than Stonehenge and even Egyptian pyramids. The mysterious complex was built almost 7,000 years ago, in the era of late neolithics, or a new stone age.
The unearthed round figure is large — about 50 feet [55 m] tall with the Pizana Tower, reports Radio Prague International. During the excavation, scientists found fragments of clayware, animal bones and stone guns in the gutter, and they were able to see its internal and external structure.
Carbon analysis of the organic residues from the excavations of the building will help scientists to determine the exact date of the construction and possibly link it to the neopolitic settlement whose tracks were found nearby.
After three centuries of popularity, this type of building suddenly disappeared from archaeological sources around 4600 B.C. Archaeologists still do not know why ancient people abandoned them.
