The western coast of the South America. 40 km from the ocean there's located the plateau of Nazca. In the beginning of the XX century when airplane flights over this area began, the unusual lines were first discovered. Previously, the lines were never mentioned neither by the chroniclers, nor by the historians. The lines were first discovered solely from the plane and this is when attention to the issue began to grow.
Please, have a look on our materials about the geoglyphs of Nazca.
