For ceuries, the misty “Andes” mouains in Peru have been hiding a dark secret. Imagine standing in the heights and facing an endless strip of rock holes; Exactly 5,200 holes that are dug in the heart of the stone with a mathematical order. This strange sight in “Moe Sierpe” or the spiral mouain, has occupied the minds of scieists for years. (Live Science)

New research published in November 2025 offers a differe and surprising answer. Archaeologists now believe that this place was not a cemetery, but a huge trading market and accouing ceer for the Chincha Empire and later the Incas. About 1.5 kilometers long, this hole strip is located right next to old roads and a defensive settleme. Holes, some of which are two meters wide and one meter deep.

For years, outlandish hypotheses have been floated, from cloud storage to gardening; But none of them matched the scieific evidence. The key to solving the puzzle was in the hands of technology. Using drones and aerial imaging, the research team discovered hidden mathematical patterns in the arrangeme of holes. These pits were not dug randomly; Rather, they are grouped in regular blocks and sections that have a strange resemblance to ancie accouing systems; But what was the physical evidence? By digging io the soil accumulated in the holes, the scieists found the remains of corn pollen. The poi is that corn does not grow at that height and with that weather condition. The only logical explanation is that humans transported large quaities of goods and food there and stored them inside the holes.

It seems that the people of the Chincha kingdom and later the Inca lords used the holes to collect taxes and tributes. The arrangeme of the holes is reminisce of “Khipu”; The same knotted ropes that the Incas used to record numbers and data. The difference in the number of holes in each block probably indicated the differe amou of tribute that each city or tribe had to pay. Imagine farmers bringing their crops to these heights with baskets woven from reeds, and governme officials filling in the holes to keep the empire’s accous. This site is no longer just an ancie work; Rather, it is a symbol of administrative and economic genius of prehistoric civilizations.
