Before the famous Inca empire, other cultures inhabit the region around Nazca and had to survive in the desert. These beautiful constructions made it possible.
Made by the Nazca culture before the Inca rule, these beautifull constructions made life in the desert easier. Underground water could be used (and it still is!) for agriculture and people´s consume with the help of this aqueducts and reservoirs. Although a dry desert, the area around Nazca has a lot of underground water. Some say that the famous Nazca lines point to this courses. Definitely the knowledge of this hidden precious water is of great value in the region.
The nazcan made more aqueducts but these are the most visited and they are in great conditions. The channels were made in S-shape in order to slow down the water flow and the spiral-shaped or shell-shaped paths provided access to the water and the underground channels for maintenance.
You can go down and taste the water (I did, although the guide adviced me not to) but don´t be to excited, it is not was cold as one wishes!
