In 2016, scientists stumbled upon this hidden corridor but were determined not to harm the 4,500-year-old monument in their quest for access. Instead, they embarked on an extensive project spanning several years to catch a sneak peek into the secrets it might hold.
Through the use of an endoscopic camera and a technique known as cosmic-ray muon radiography, experts have successfully mapped the corridor, confirming its dimensions at 30 feet (9 meters) in length and 7 feet (2.1 meters) in width.
They believe that its purpose was likely to redistribute the weight of the pyramid, either around the entrance or to support an as-yet-undiscovered chamber.
The Great Pyramid of Giza, standing at a towering 479 feet (146 meters) and originally constructed as royal burial chambers circa 2560 BC, remains the sole survivor among the Seven Wonders of the Ancient World.
Until the erection of the Eiffel Tower in 1889, it was still the tallest human-made structure ever built.
Authorities made the revelation today and expressed that this unfinished corridor, located behind the primary entrance, could potentially enrich our understanding of the pyramid's construction. According to Mostafa Waziri, head of Egypt's Supreme Council of Antiquities, it may have been constructed to alleviate the pressure on the main entrance, situated 22 feet (7 meters) below, or to support another concealed chamber or space.
It was likely built to relieve the weight of the pyramid on either the main entrance, 22 feet (7 meters) below, or on another as yet undiscovered chamber or space, according to Mostafa Waziri, head of Egypt's Supreme Council of Antiquities.
He told to reporters after a press conference in front of the pyramid, state: "We're going to continue our scanning so we will see what we can do ... to figure out what we can find out beneath it, or just by the end of this corridor."
Additionally, it is believed that five chambers above the king's burial chamber in a different section of the pyramid were designed to redistribute the structure's immense weight. Waziri even speculated that the pharaoh might have had more than one burial chamber.
The discovery of the corridor was facilitated by cosmic-ray muon radiography, a technique developed by experts at the University of Nagoya, Japan, which measures the radiation passing through the pyramid walls.
Once this technique had provided a clear corridor map, researchers seized the opportunity to employ a small camera similar to those used in medical procedures.
