Inca quarries and road network found in Cañete
Archaeologists have discovered Inca quarries and a road network in Cerros de Quilmaná and Cerro Quinta Freno, in the province of Cañete, Peru.
According to a press release announced by the Peruvian State, the quarries were used to supply material for the construction of walls at the Inca sites of El Huarco in Cerro Azul and Vilcahuasi in San Luis de Cañete.
The team have also found a network of roads and pathways linked to support the transportation of the sculpted stone blocks. According the researchers, these routes indicate the significant role the quarries held as a stone working centre within the Inca State during the 16th century.
With the rise of the Inca Empire, a large road network connected all parts of their territory spanning over 40,000 kilometres (25,000 miles), which is considered one of the most extensive and advanced transportation systems in pre-Columbian South America.
During the colonial period following the Spanish conquest of Peru, the Conquistadors initially used the Inca roads to reach the capital city of Cusco, however, their reliance on horses and ox carts, unsuitable for such terrain, led to the abandonment of most of the network.
“The discovery of this network of Inca roads and the quarries offer valuable research opportunities, revealing new insights into the technology of the Inca master stonemasons, in addition to the extraction, carving and polishing of lithic blocks that were used in various imperial works,” said the press release.
The road and path network also provides new information on how the roads served as transport mechanisms for the transfer of worked and quarried stone to the Inca settlements located in the coastal territories.
There is an archaeological expedition scheduled for 2024 to survey the quarries, aiming to conserve these sites for potential future tourism.

A study of archaeological sites in Winchester, England, has revealed that red squirrels served as a host for Mycobacterium leprae strains that caused leprosy in people.
Leprosy is one of the oldest recorded diseases in human history and is still prevalent to this day in Asia, Africa, and South America.
It has previously been suggested that the extensive trade of red squirrel fur, greatly valued during medieval times, could have contributed to the leprosy epidemic in medieval Europe.
The results of the study, published in the journal Current Biology, studied 25 human and 12 squirrel samples from two medieval sites in Winchester.
During this period, the city had strong connections to the fur trade and housed the leprosarium, a hospital that treated people with Hansen’s disease (leprosy) caused by Mycobacterium leprae bacteria.
Verena Schuenemann of the University of Basel in Switzerland, said: “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy.”
The study found that the medieval red squirrel strains were more closely related to human strains in Winchester, rather than to modern squirrel strains from England – suggesting an independent circulation of Mycobacterium leprae strains.
“Our findings highlight the importance of involving archaeological material, in particular animal remains, into studying the long-term zoonotic potential of this disease, as only a direct comparison of ancient human and animal strains allows reconstructions of potential transmission events across time,” says Sarah Inskip of the University of Leicester, UK, a co-author on the study.

Archaeologists from the Uncovering Roman Carlisle project have discovered a rare lump of Tyrian purple at the grounds of the Carlisle Cricket Club in Carlisle, England.
The project is a community supported excavation by Wardell Armstrong, focusing on uncovering a Roman bath house found in 2017.
The bath house is located near the Roman fort of Uxelodunum (meaning “high fort”), also known as Petriana, in the Carlisle district of Stanwix.
Uxelodunum was constructed to control the territories west of present-day Carlisle and an important crossing on the River Eden. The fort was garrisoned by the Ala Petriana, a 1,000-strong cavalry unit, whose members were all granted Roman citizenship for valour on the field.
Previous excavations at the bath house have discovered colossal sandstone heads depicting Roman gods, in addition to engraved gems known as intaglios, figurines, animal bones, and imperial-stamped tiles.
During the latest season of excavations, archaeologists found a mysterious lump of a soft purple substance. The substance was tested by researchers from Newcastle University, revealing that it contained levels of Bromine and beeswax.
According to the researchers, the substance is Tyrian purple, a coloured dye associated with the Imperial Court in the Roman Empire. Tyrian purple is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex.
Frank Giecco, Technical Director at Wardell Armstrong, said: “For millennia, Tyrian Purple was the world’s most expensive and sought after colour. It’s presence in Carlisle combined with other evidence from the excavation all strengthens the hypothesis that the building was in some way associated with the Imperial Court of the Emperor Septimius Severus which was located in York and possibly relates to an Imperial visit to Carlisle.”
“It’s the only example we know of in Northern Europe – possibly the only example of a solid sample of the pigment in the form of unused paint pigment anywhere in the Roman Empire. Examples have been found of it in wall paintings (like in Pompeii) and some high status painted coffins from the Roman province of Egypt,” said Giecco.
