A vertical section of the Great Pyramid of Giza, sometimes referred to as "air shafts."
"Star shafts" commonly refers to two narrow ducts leading out of the King's Chamber of the Great Pyramid of Giza. It may also refer to two shafts in the walls of the Queen's Chamber, though these are discussed less frequently due to being blocked off on both the outside and inside of the pyramid.
Shafts of this nature have not been discovered in any other pyramids as of yet. [1] Initially they were presumed to be ventilation shafts, but doubt has been cast on this theory due to the shafts not leading all the way to the outside. This same fact also casts doubt on the theory that the shafts were used to observe certain stars. In 2010, researchers from Leeds University developed a robot that traversed the shaft and used an endoscopic camera to look through the hole previously drilled through the stone blocking the path to the outside, which revealed a small chamber with red ochre markings on the floor and followed by another large stone blocking the path.

In the north and south walls of the King's Chamber are two narrow shafts, commonly known as "air shafts". They face each other and are located approximately 0.91 m (3.0 ft) above the floor, 2.5 m (8.2 ft) from the eastern wall, with a width of 18 and 21 cm (7 and 8.5 in) and a height of 14 cm (5.5 in). Both start out horizontally for the length of the granite blocks they go through before changing to an upwards direction. [3] The southern shaft ascends at an angle of 45° with a slight curve westwards. One ceiling stone was found to be distinctly unfinished which Gantenbrink called a "Monday morning block". The northern shaft changes angle several times, shifting the path to the west, perhaps to avoid the Big Void. The builders had trouble calculating the right angles, resulting in parts of the shaft being narrower. [4] Nowadays they both commute to the exterior. If they originally penetrated the outer casing is unknown.
In the Great Pyramid of Giza there are two narrow shafts, in the north and south walls of the King's Chamber. Alexandre M. Badawy suggested that the south shaft pointed to Orion's Belt during the period of the construction of the Giza pyramid complex. [5] While this may be true, the shafts could not have been used to actually observe the stars due to the intentionally placed stones blocking the path. Virginia Trimble posited that the north shaft was meant to point towards the north circumpolar stars, The Indestructibles. The Ancient Egyptians believed that these stars were closely associated with eternity and the afterlife, so this northern shaft possibly could have been a way whereby the soul of the deceased king might ascend to the stars. [6]
Another common theory is that the shafts were merely "air vents" for ventilation. Of course the dead do not need air vents, but they may have been useful as such during the construction of the pyramid. However, at some point in the construction, the shafts were intentionally sealed with large stones, so whether or not they could have been used for ventilation is uncertain. Furthermore, the lack of shafts in the other pyramids casts doubt on this theory. [1]
The theory that is most widely accepted today[ citation needed ] is that of the shafts pointing towards certain stars/asterisms that were important to the Egyptians. It is expected that at the time of the pyramid's construction (circa 2500 BC), the shafts aligned with the transit points of Alpha Draconis (which is projected to have been the star closest to the north celestial pole), Orion's Belt, Sirius, and Beta Ursae Minoris. The star shafts were presumably meant to direct the spirit of the pharaoh to these stars; Alpha Draconis the pole star, Beta Ursa Minoris one of The Indestructibles, Orion representing the deity Osiris, and Sirius representing his consort Isis. [7]
In 2010, researchers from Leeds University had finished construction of a robot specifically designed to traverse the shafts and attempt to determine their true purpose. The robot successfully navigated through all 60 meters of one shaft, collecting nine hours of video footage. [8] Upon reaching the large stone at the end of the shaft, the robot managed to get a camera past it. On the other side, a small chamber with intricate symbols on the floor was discovered. Rob Richardson, Professor of Robotics at Leeds, stated “given the artwork, it is likely the shaft served a bigger purpose than act as an air vent. But what that bigger purpose was remains a mystery.” [2]
Furthermore, at the other end of the small decorated chamber, was another large stone blocking the shaft; due to the robot not being able to get past the second stone, what lies past it continues to remain a mystery. However, the robotic exploration project had to be cut short due to growing security problems in Egypt. [2]
The Great Pyramid of Giza is the largest Egyptian pyramid and served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom. Built in the early 26th century BC, over a period of about 27 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northern end of the line of the three pyramids at Giza.
The pyramid of Djoser, sometimes called the Step Pyramid of Djoser, is an archaeological site in the Saqqara necropolis, Egypt, northwest of the ruins of Memphis. The 6-tier, 4-sided structure is the earliest colossal stone building in Egypt. It was built in the 27th century BC during the Third Dynasty for the burial of Pharaoh Djoser. The pyramid is the central feature of a vast mortuary complex in an enormous courtyard surrounded by ceremonial structures and decoration. Its architect was Imhotep, chancellor of the pharaoh and high priest of the god Ra.
Khufu or Cheops was an ancient Egyptian monarch who was the second pharaoh of the Fourth Dynasty, in the first half of the Old Kingdom period. Khufu succeeded his father Sneferu as king. He is generally accepted as having commissioned the Great Pyramid of Giza, one of the Seven Wonders of the Ancient World, but many other aspects of his reign are poorly documented.
The Great Sphinx of Giza is a limestone statue of a reclining sphinx, a mythical creature with the head of a human and the body of a lion. Facing directly from west to east, it stands on the Giza Plateau on the west bank of the Nile in Giza, Egypt. The face of the Sphinx appears to represent the pharaoh Khafre. The original shape of the Sphinx was cut from the bedrock, and has since been restored with layers of limestone blocks. It measures 73 m (240 ft) long from paw to tail, 20 m (66 ft) high from the base to the top of the head and 19 m (62 ft) wide at its rear haunches.
The Red Pyramid, also called the North Pyramid, is the largest of the pyramids located at the Dahshur necropolis in Cairo, Egypt. Named for the rusty reddish hue of its red limestone stones, it is also the third largest Egyptian pyramid, after those of Khufu and Khafre at Giza. It is also believed to be Egypt's first successful attempt at constructing a "true" smooth-sided pyramid. Local residents refer to the Red Pyramid as el-heram el-watwaat, meaning the Bat Pyramid.
The Bent Pyramid is an ancient Egyptian pyramid located at the royal necropolis of Dahshur, approximately 40 kilometres (25 mi) south of Cairo, built under the Old Kingdom Pharaoh Sneferu. A unique example of early pyramid development in Egypt, this was the second pyramid built by Sneferu.
The Egyptian pyramids are ancient masonry structures located in Egypt. Sources cite at least 118 identified "Egyptian" pyramids. Approximately 80 pyramids were built within the Kingdom of Kush, now located in the modern country of Sudan. Of those located in modern Egypt, most were built as tombs for the country's pharaohs and their consorts during the Old and Middle Kingdom periods.
The pyramid of Khafre or of Chephren is the middle of the three Ancient Egyptian Pyramids of Giza, the second tallest and second largest of the group. It is the tomb of the Fourth-Dynasty pharaoh Khafre (Chefren), who ruled c. 2558−2532 BC.
The Giza pyramid complex in Egypt is home to the Great Pyramid, the Pyramid of Khafre, and the Pyramid of Menkaure, along with their associated pyramid complexes and the Great Sphinx. All were built during the Fourth Dynasty of the Old Kingdom of ancient Egypt, between c. 2600 – c. 2500 BC. The site also includes several temples, cemeteries, and the remains of a workers' village.
Pyramidology refers to various religious or pseudoscientific speculations regarding pyramids, most often the Giza pyramid complex and the Great Pyramid of Giza in Egypt. Some "pyramidologists" also concern themselves with the monumental structures of pre-Columbian America, and the temples of Southeast Asia.
Robert Bauval is a Belgian author and lecturer, perhaps best known for the fringe Orion Correlation Theory regarding the Giza pyramid complex.
Meidum, Maydum or Maidum is an archaeological site in Lower Egypt. It contains a large pyramid and several mudbrick mastabas. The pyramid was Egypt's first straight-sided one, but it partially collapsed in ancient times. The area is located around 72 kilometres (45 mi) south of modern Cairo.
The Hall of Records is a purported ancient library that is claimed to exist underground near the Great Sphinx of Giza in Egypt. The concept originated with claims made by Edgar Cayce, an American who claimed to be clairvoyant. He said in the 1930s that the civilization of Atlantis was destroyed around 10,500 BC and that Atlantean refugees built the Hall of Records at Giza to preserve their knowledge. Cayce's assertions had many precursors, particularly the pseudoscientific theories about Atlantis that Ignatius Donnelly promulgated in the late 19th century and claims about hidden chambers under the Sphinx that were made by H. C. Randall-Stevens and Harvey Spencer Lewis in the years before Cayce described the Hall of Records.
The Layer Pyramid is a ruined step pyramid dating to the 3rd Dynasty of Egypt and located in the necropolis of Zawyet El Aryan. Its ownership is uncertain and may be attributable to pharaoh Khaba. The pyramid architecture, however, is very similar to that of the Buried Pyramid of king Sekhemkhet and for this reason is firmly datable to the 3rd Dynasty.
Egyptian pyramid construction techniques are the controversial subject of many hypotheses. These techniques seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. Most of the construction hypotheses are based on the belief that huge stones were carved from quarries with copper chisels, and these blocks were then dragged and lifted into position. Disagreements chiefly concern the methods used to move and place the stones.
The Indestructibles was the name given by ancient Egyptian astronomers to two bright stars which, at that time, could always be seen circling the North Pole. The name is directly related to Egyptian belief in constant North as a portal to heaven for pharaohs, and the stars' close association with eternity and the afterlife. These circumpolar stars are now known as Kochab, in the bowl of Ursa Minor or, the Little Dipper, and Mizar, in Ursa Major, at the middle of the handle of the Big Dipper.
The Upuaut Project was a scientific exploration of the so-called "air shafts" of the Great Pyramid of Giza, which was built as a tomb for Fourth Dynasty pharaoh Khufu. The Upuaut Project was led by Rudolf Gantenbrink under the auspices of the German Archaeological Institute in Cairo during three campaigns. According to Bauval, it was "marshalled into two stages: the first stage, to improve ventilation in the Great Pyramid using the shafts in the King's Chamber, and the second stage to explore the presumed 'abandoned' shafts in the Queen's Chambers." The latter was accomplished by sending a miniature mobile robot designed by Rudolph Gantenbrink, named Upuaut-2, into the shafts.
The Orion correlation theory is a fringe theory in Egyptology attempting to explain the arrangement of the Giza pyramid complex.
The Djedi Project was an exploration of the interior of the Great Pyramid of Giza. The project team was made up of international and Egyptian experts. The name derived from Djedi, the ancient Egyptian magician consulted by Pharaoh Khufu when planning his famous pyramid. As Dr. Zahi Hawass announced on his blog: "The purpose of this project is to send a robotic tunnel explorer into the two "air shafts" that lead from the Queen's Chamber of the Great Pyramid of Khufu to gather evidence to determine the purpose of the shafts."
The pyramid of Senusret II at El Lahun is the pyramid complex constructed for the pharaoh Senusret II in the Twelfth Dynasty.
