The Cantalloc Aqueducts are one of the Nazca civilisationís greatest achievements. Cursed with a barren, dry and rocky desert in which to live, with only the narrowest of valleys with the narrowest of areas suitable for agriculture, developing hydraulic engineering was a necessity for the ancient Nazca people.
Between 30 and 50 underground channels were constructed about 1500 years ago, bringing water from rivers higher in the valley to the centre of their civilisation. Spanning kilometres, trenches were dug that were lined with stones and covered by wood from local trees before being reburied.
At Cantayo, 4km from the modern city of Nasca, we find about 17 open wells. These have paths that spiral down to the level of the running water that provide access to this precious resource, but possibly also access to clean or repair the structures in case of an earthquake.
