Viaje al Interior de la Tierra III

Tierradentro...The culture and the area known as Tirradentro are still two misteries for modern archeologists and others. Nobody knows for sure how the pre-Culumbian civilization built "hipogeos", underground tombs, without electricity or other light source besides fire, wich could have absorved all the oxygen of inside the caves and the builders would have died. Below 8 meters from the surface, geometric figures, faces and animals bring back the voices of people who lived centuries before Colombia turned into a big absurd.
