The ancient fortress site of Tiahuanaco (Tiwanaku) in western Bolivia is still revealing secrets thousands of years after its peak as capital of an empire, and home to one of the most important civilizations prior to the Inca. Archaeologists from the Tiahuanaco Archeological Research Center have discovered an underground pyramid at the site using ground-penetrating radar.
According to Fox News Latino, the Bolivian government has announced excavations are set to begin this summer on the new find at the Kantatallita area of Tiahuanaco, 71 kilometers (44 miles) west of La Paz.
Using ground-penetrating radar, researchers also have reportedly found “underground anomalies” which they suspect might be monoliths, but further analysis will be carried out before reaching official conclusions.
Ludwing Cayo, director of the Tiahuanaco Archeological Research Center told EFE News Agency that Tiahuanaco will be undergoing further investigations over the next five years. This is welcome news to some, as the site and stone monuments may have suffered from exposure weathering 4,000 meters above sea level.
