Linee di Nazca
Nazca is, perhaps, one of the most famous cities of Peru due to the presence of its famous lines whose realization and their meaning are, to date, the object of various hypotheses and myths. What has been found is that the lines can be divided into three chronological phases: the Chavín period (500-300 ac), the Paracas period (400-200 ac) and the Nazca phase (200 ac-500 dc) which produced the great majority of lines.
These lines are geoglyphs, lines drawn on the ground, of the Nazca desert, an arid plateau that stretches for about eighty kilometers between the cities of Nazca and Palpa, in southern Peru. The more than 13,000 lines form over 800 drawings, which include the stylized profiles of common animals in the area (the whale, the parrot, the lizard over 180 meters long, the hummingbird, the condor and the enormous spider about 45 meters).
The lines are drawn by removing the stones containing iron oxides from the desert surface, thus leaving a contrast with the lighter gravel below.
The Nazca plain is not windy and the climate is quite stable so the giant designs have remained intact for hundreds of years.
