Ancient Peruvian

Founded in 1640 Important viticulture center, it was severely damaged by the earthquake of 15 August 2007. It is also a tourist center of a certain importance, thanks to the natural heritage represented by the Islas Ballestas Archipelago, located in the Paracas National Reserve and reachable with few miles of sailing from the port of Pisco.

Quote by Alessandro Brizzi

“An aerial photo of 1931, taken by photographer and geographer Robert Shippee, is the first known documentation of Mount Sierpe, an ancient Peruvian archaeological site, popularly known as the strip of holes, brought to light by archives, after an archaeologist received a phone call from a man who asked about the link between aliens and Inca in southern Peru.

In Mount Sierpe, in the Valle di Pisco, thousands of aligned holes have attracted the attention of archaeologists. Two years ago, he was telephoned by a Pittsburgh resident who signaled me a television program, which claimed the existence of a Peruvian site “work of extraterrestrials“.

Although I am an expert in the field, I had never heard of the site. However, after seeing the coordinates on Google Earth, I decided it was worth investigating the case.

“I had never seen anything like this”.

It seems to be made up of thousands of small artificial depressions aligned for about a mile (just under two kilometers). “I’ve never seen anything like it,” “It looked like a really unique site.” Disoriented by the site and very uncertain about the purpose of the holes, I began to speculate: “It could have been part of a defensive structure, or served the trail of a path, or it could also be a geoglyph, in the tradition of the nearby Nazca lines” .

Previous generations of archaeologists knew about the site, excavations had been conducted, but no artifact had been found near the holes. There was no agreement as to when they were made, or from what culture. The mystery deserved a deepening. In the 2015 field season, From the bottom, rows of creeping holes up the slope offered an impressive view. “Really, it’s very impressive”, “I’ve never seen anything like this in my entire career”. We immediately found a small amount of pottery dating back to shortly before the Spaniards invaded Peru, when the Inca ruled this part of the territory.

Incas, among them, were the giants Original article by Alessandro Brizzi.


There were also other signs that it could be an Inca site. “I began to suspect that it could be dated to the Inca period, because at the base of the site there are tombs similar to those in the Chincha valley, datable to the time of the Incas”. The holes were made in various ways, some dug into artificial mounds of soil and others composed of small rock structures superimposed on the ground surface. No one was dug into the volcanic rock of the hill, as some believed. We have also observed that the strip is divided into several groups, which we have called blocks, each of which has different patterns of holes. Using a drone, we collected aerial images and generated a new detailed map of the Strip of Holes, which is estimated to be composed of 5000 – 6000 cavities. After the examination and study of the site, I began to think that the initial suspicion was right and that it could date back to the period when the Inca had conquered the area. Not only were the remains of an Inca road nearby, but also a series of colcas, warehouses from the Inca period. Together with the discovery of Inca pottery near the strip, these findings seem to suggest that the strip of holes dates back to roughly the fifteenth century, after the Inca Empire had subjugated the Chincha people, who were native to the region. It was all circumstantial, but it seemed to be fine. We also thought that the holes could have been used to store something, but what and why it was not yet clear. It was not clear that such ancient populations would have the necessity to build works that are seen from above as tracks, or unequivocal signs of docking!
