How the Causeway for the Great Pyramid of Egypt Was Found After Decades of Searching

Dozens of foreign missions carried out over three decades using the latest high-tech instruments failed to find the causeway of the Great Pyramid of Giza. But in 2015, unexpectedly, the passage was finally located by a local resident living near the Giza Plateau, who was illegally digging beneath his home when he discovered a tunnel leading to the Pyramid of Khufu, the largest of the three pyramids in Giza.

Arabic news source reported that a resident in the village of El Haraneya in Giza, a prohibited area for drilling, began digging beneath his house to a depth of about 10 meters (33 feet), when he discovered a passage consisting of huge stone blocks.

The Minister of Police for Tourism and Antiquities was alerted to the discovery and security forces immediately placed a cordon around the property. The Ministry of Antiquities was notified of the incredible finding, and archaeologist Kamal Wahid was placed in charge of a committee to investigate. In its report, the committee confirmed the finding of the corridor leading to the Great Pyramid, the oldest and largest of the three pyramids in Giza.

The Khufu pyramid complex consisted of a Valley Temple near the Nile River, which was once connected to a long causeway that led to the Temple of Khufu (also known by the Hellenized name, Cheops). This temple was connected to the pyramid.  The discovery of basalt paving and limestone walls suggests the Valley Temple is buried beneath the village of Nazlet el-Samman.

Despite decades of research and excavations, only a few remnants of the causeway (a covered, raised road, like an above ground tunnel) which linked the pyramid with the Valley Temple had been found before 2015. 

Ancient Greek Historian Herodotus, who visited the Great Pyramid in the 5th century BC, described the causeway as being about a kilometer (0.6 miles) long, though this account is contested by modern Egyptologists. Former Minister of State for Antiquities, Dr. Zahi Hawass, estimated the total length of the causeway as being about 825 meters (2706.69 ft.).

In his second book of ‘Histories’, Herodotus described the causeway as being totally enclosed and decorated in fine reliefs. He wrote:

there passed ten years while the causeway was made by which they drew the stones, which causeway they built, and it is a work not much less, as it appears to me, than the pyramid; for the length of it is five furlongs and the breadth ten fathoms and the height, where it is highest, eight fathoms, and it is made of stone smoothed and with figures carved upon it. For this, they said, the ten years were spent, and for the underground chambers on the hill upon which the pyramids stand

The causeway of the second pyramid of Giza, Khafra’s pyramid, survived to some degree, however, it is in Saqqara, at the causeway of Unas’ pyramid, where one is able to get a better perspective for what they once looked like.  The Unas’ causeway, which even has a small section of the roof remaining, is the best surviving causeway.

“It consisted of a covered passageway, 720m long, its interior surfaces decorated with high quality reliefs depicting a range of colourful scenes,” writes the Egyptian sites blog . “The walls were lit by a slit in the roof of the causeway which ran along the whole of its length. The theme of decoration on the causeway walls progresses from the living world in the east to the land of the dead in the west.”

Two years later, in 2017, scientists made another fascinating discovery at the Great Pyramid. Using powerful scanning technology, they detected a large space within the famous landmark. It has been suggested that the space may be a hidden chamber, an aerial shaft, or a sealed-off construction passage. But the exact purpose is still a mystery. That space is the first major inner structure found in the pyramid of Khufu since the 19th century. It is hoped that as investigations progress, we may have a much richer understanding of the great pyramid complex at Giza.

I don't think it's about money or tourism so much that the actual ramifications of the finds destroy the current linear advancement theory. The sphinx clearly has water erosion on it - and LOTS of it. There hasn't been water in the Giza Plateau for some 12000 years. Divulging the truth would cause the re-writing of all history books and the explanation that there were indeed advanced civilizations long before the current one.

The water erosion is both accepted and disputed, that is to say some have shown that wind can erode sand stone in a similar fashion when an abrasive such as sand is present. Sandblasting. Still, it could be water that did it which does point to pre-flood or earlier times...pre-iceage? The head of the Sphinx is too small for the body, they could and would have done better than that. I think it got reworked at some point.

I believe the earth is recreated every 7000 years in alignment with the biblical story. Look to the one quarter turn of the precessionary cycle to determine the length of an age.

recreated how? New planet from scratch or just ploughed over and replanted?
