Khufu’s pyramid, known as the great pyramid of Giza, is the oldest and largest, rising at 481 feet (146 meters). Archeologists say it was the tallest structure in the world for about 3, 800 years.
Three pyramids, those of Khufu, Khafre and Menkaure are perfectly aligned with the stars that make up the constellation of Orion’s belt.
Furthermore, the Descending Passage of the Great Pyramid points to the pole star known as Alpha Draconis.
The three pyramids in Giza Necropolis are the most famous Egyptian pyramids but in fact, as many as about 140 pyramids in total have been discovered in the area of the Ancient Egypt.
Though most people think of Egypt when they read pyramid facts, there are actually many similar structures built all over the world.
In fact, the largest pyramid in the world is actually in Mexico.
The Sphinx is a 73.5-meter (241 ft.) long monument built during the reign of Khafra. The creature is a mythical being commonly found in Greek, Egyptian and even South Asian ancient architecture.
The oldest pyramid in Egypt is believed to be over 4500 years old.
The Great Pyramid of Giza is estimated to be made of around 2,300,000 blocks of stone. Many weigh between 2 and 30 tons. Some weigh more than 50!
The oldest Egyptian pyramid is believed to be the Pyramid of Djoser which was built in the Saqqara Necropolis during the 27th century BC.
Khafre and Menkaure’s pyramids are much smaller and simpler in design than Khufu’s massive structure. When first built, the pyramids were covered in white limestone much of which eroded over the years.
Although many people associate pyramids with hieroglyphics, there have been no writing or hieroglyphics found inside the Great Pyramid of Giza.
The Great Pyramid faces true north. In fact, it’s the most accurately aligned to true north of any structure on the planet. Despite being made millennia ago, the pyramid faces that direction with just 3/60th a degree of error. However, this is probably because the North Pole shifts over time. Therefore, at one time, the pyramid was spot on.
The Great Pyramid also has slightly concave sides. This is the only pyramid with that feature.
Inside the pyramid is the “King’s Chamber” featuring a granite coffer. The coffer is too big for the passage it would have had to come through, leading many to believe the Great Pyramid was built around it.
As these last two pyramid facts aren’t strictly focused on the structures, I hope you’ll forgive me. But get this: the coffer was made from one block of granite. It turns out the ancient Egyptians used a fixed point drill with bits made from hard jewels (possible sapphires) and applied a force of 2 tons.
Three of the pyramids actually had swivel doors at their entrance originally: The Great Pyramid and those of Huni and Sneferu. All were family members (son, father, and grandfather, respectively)
Contrary to popular depictions, the Egyptian pyramids were not built by large groups of slaves or prisoners, many historians say. Egyptians were employed and archeologists estimate the workers would have had to set a 2.5 to 15-ton block every two and a half minutes to finish Khufu’s pyramid in about 30 years.
Contrary to popular belief, the pyramids probably were not built by slaves or prisoners but regular paid workers.
Inside the Egyptian pyramids, the temperature actually stays relatively constant around 20 degrees Celsius.
