REVEALED: Great Pyramid of Giza were constructed using long-lost branch of the Nile river that dried up more than 2,000 years ago and helped workers transport 2.3m blocks used to build them
- How the Great Pyramid of Giza was built has been a mystery for centuries
- Theories suggest men transported the 2.3 million stone blocks across 500 miles of land
- The new study found evidence to support the idea that workers used the Nile river to ferry the giant stones, some of which weighed 15 tons
- The team uncovered the Khufu branch flowed close to where the Great Pyramid of Giza sits
New evidence suggests a long-lost channel of the Nile, known as the Khufu branch, flowed close to where the Great Pyramid of Giza sit and was used to transport the 2.3 million stone blocks to construct the structures before it dried up around 600 BC.
This discovery is supported by text in a more than 4,000-year-old papyri that describes boats used the Nile to move blocks from the cliffs opposite Giza and from the Red Sea to build the pyramids.
A team of French researchers, working with others from China and Egypt, analyzed rock layers surrounding the pyramids, allowing them to see the timeline and flow of the Khufu branch to determine its levels were once high enough to reach Giza.
Without this arm of the Nile, according to the researchers, it would have been impossible for the pyramids to be built 4,000 years ago, as ancient Egyptians would have had to transport the blocks 500 miles over land – and some of which weighed 15 tons.
Archaeologists believe they found evidence of a long-lost arm of the Nile river that ancient Egyptians used to transport stone on boats to Giza and use to build the three pyramids

The Great Pyramid of Giza – the oldest and only survivor of the Seven Wonders of the Ancient World – was constructed by three pharaohs from about 2550 to 2490 BC.
The tallest was commissioned by Khufu, the one that sits behind the two was built by his son Khafre and the front pyramids was constructed under the rule of Menkaure.
But exactly how this was done has been one of the world’s greatest enigmas.
Now, archaeologists believe it was done by boats traveling through a now gone arm of the Nile.

The team used pollen-derived vegetation patterns to reconstruct 8,000-year-old fluvial variations on the Giza floodplain.
Fluvial is a stream-related process in which weathered sediment is picked up by flowing water and moved to new locations, which holds clues to where water bodies may have once flowed.
The team also looked at evidence of marsh plants, semiaquatic plant that grow in soft wet land and edges of lakes, and found the Khufu branch remained at high levels in the area long enough for nature to consider it permanent, Phys.org reports.
The study also determined that the port used to transport these stones thousands of years ago is more than four miles west of the Nile – much closer than trekking 500 miles over land.
‘Our results show that Giza’s waterscapes responded to a gradual insolation-driven aridification of East Africa, with the lowest Nile levels recorded at the end of the Dynastic Period,’ the teams wrote in the study published in PNAS.
The pyramids include 2.3 million blocks made of limestone and granite, averaging about 2.5 tons each. The stones, however, are believed to have first been cut and then transported to the site
‘The Khufu branch remained during the reigns of Khufu, Khafre and Menkaure, facilitating the transportation of construction materials to the Giza Pyramid Complex.’
The pyramids include 2.3 million blocks made of limestone and granite, averaging about 2.5 tons each.
The stones, however, are believed to have first been cut and then transported to the site.
The ancient Greek historian Herodotus, who lived from 484 to 425 C, wrote that it took 20 years and the labor of 100,000 men to finish the wonder.
Archaeologists, however, argue there were around 20,000 men.
The mummified remains and treasured once buried in the pyramids were stolen by grave robbers and the tops have since crumbled – the giant structures are much smaller than when they were first built.
However, millions of people flock to Egypt to feast their eyes on the wonder.
THE MYSTERY OF THE GREAT PYRAMID OF GIZA
For more than 4,500 years, Egypt’s pyramids have kept their secrets hidden deep within the labyrinth of passages and chambers that lie inside their towering stone structures.
But the long-running row over whether the Great Pyramid of Giza is hiding a network of previously undiscovered tunnels behind its stone walls has now been answered.
The researchers confirmed the find using cosmic particles known as muons to scan the Great Pyramid of Giza.
They used the scans to create maps to reveal the internal structure of the 479 feet (146m) high pyramid.
Last year thermal scanning identified a major anomaly in the Great Pyramid, the largest and oldest of the pyramids at Giza and one of the seven Wonders of the Ancient World.
Those scans identified three adjacent stones at its base which registered higher temperatures than others.
The Egyptian Museum in Cairo on Thursday began putting on display the country’s oldest papyruses, which date back 4,500 years, detailing the daily life of the pyramid-builders.
This led to theories that they may be hiding a secret chamber that had yet to be discovered.
A team of experts then set up the ScanPyramid’s project to use muons, tiny subatomic particle that are typically produced by cosmic rays smash into atoms on Earth, to peer through the Pyramid’s huge stone blocks, some of which weight up to 15 tons.
Dr Hawass has in the past been sceptical of the usefulness of conducting such scans.
He recently clashed publicly with British Egyptologists over their theory that a secret burial chamber may be hidden behind the walls of Tutankhamun’s tomb in his pyramid in the Valley of the Kings.
