The Great Pyramid is the oldest and tallest of the three Pyramids of Giza.
There is considerable debate about many aspects of the Pyramid, from how it was constructed and how many laborers were needed, to the purpose of the structure.
It is the only one of the Seven Ancient Wonders of the World to still be in existence today.
1. The pyramids of Giza were the first to be built
The pyramids of Giza were the first to be built. Pharaoh Djoser built a step pyramid in Saqqara south of Giza around 2630 BCE. Initially, tombs of kings and queens were underground.
Djoser’s tomb was constructed before that of Sneferu whose Red pyramid was the first true pyramid to be completed between 2613 and 2589 BCE.
2. The interior of the pyramid has three chambers
The pyramids were designed as tombs. The Great Pyramid, therefore, contains three burial chambers that were intended to house Khufu and a supplication of goods and treasures that he was to take with him in the afterlife.
When entering the pyramid, there is a passage that descends about 354 feet (ca. 108 m) into the bedrock, then levels off. It continues another 29 feet (ca. 9 meters) to an unfinished, underground chamber.
After which there is a hole in the roof that leads to the ascending passage, a 129-foot stretch rising to the Grand Gallery, this is the only known pyramid with a passage that slopes upward.
At the entrance of the Gallery is a passage to the Queen’s Chamber.
There is a series of shafts, stretching from the north and south walls.
These have been studied multiple times but their purpose is yet to be known.
3. The pyramid had an invisible door
It is believed that the pyramid once had a swivel door that weighed up to 20 tons. One could only push open the door from the inside and was not detectable from the outside.
The doors were so heavy that the opening mechanism was only discovered when the Great Pyramid was being studied by scientists.
They realized that they were two hue swivel doors. The Egyptian’s ability to balance the 20-tonne doors to order to create this effect has remained a mystery to date.
4. The Other Two Pyramids Are For Khufu's Son And Grandson
The Great Pyramid is just one of the three major pyramids in Giza. The second-oldest one is the Pyramid of Khafre which was built as a tomb for Khafre, Khufu’s son. It is the second-tallest pyramid in Giza. Khafre ascended to the throne after the short-lived reign of Redjedef, who was likely his older brother and was Khufu’s successor. He reigned from approximately 2558 to 2532 BCE, but the exact timeline has never been established.
The third and the smallest pyramid is the Pyramid of Menkaure, Khafre’s son. It is not totally clear, but he most likely succeeded his father as king and reigned for 18 or 28 years. It was unfinished at his death, but his successor Shepseskaf had the mortuary temple finished. Important sculptures were found in the tomb.
5. It was The Tallest Human-Made Structure For 3800 Years
The pyramid was the tallest structure made by humans for a record 3,800 years until the completion of the Lincoln Cathedral (England) in 1300 CE, which is 520 feet tall (160 m). The pyramid is 480.9 feet (146.6 m) tall and has a base of 754 feet (230 m) on each side. However, other scholars point to Eiffel Tower completed in 1889 as the structure that first surpassed the pyramid, measuring in at 1,063 feet (324 m).
