Aqueducs de Nazca au Pérou

Les puquios sont un ancien système d'aqueducs souterrains de l'époque précolombienne. Ils sont situés près de la ville de Nazca, au Pérou. Sorte de trous en spirale creusés dans le sol, ils servent à amener de l'eau dans des zones arides grâce à la force du vent qui, piégée par la spirale, provoque un courant. Sur les 36 puquios découverts, la plupart fonctionnent encore. Source Wikipédia
