The Great Pyramid of Giza. The only one of the Seven Wonders of the Ancient World that still stands today is one of the greatest monuments ever erected on Earth.
Located on the outskirts of Cairo, this pyramid is the largest of the three Pyramids at the Giza plateau and is estimated to have been completed in the year 2560 BC destined to guard the mummified remains of Khufu pharaoh of the fourth dynasty of Ancient Egypt.
The ancient architect who carried out the work was Hemiunu, a relative of the Pharaoh, who revolutionized the laws of physics by building what was then and well into the nineteenth century the highest building in the world.
What makes the pyramid an architectural wonder and one of the Seven Wonders of the World is the fact that each of the stones used in its construction weighs around if not more than two tons. And the Pyramid is made up of more than two million of such stones.
It is estimated that the Pyramid was built in twenty years.
As for the interior of the pyramid, it is composed of three main chambers: the King’s Chamber, the Queen’s Chamber, and the Underground Chamber, the latter located in beneath the surface.
It also has a space called Great Gallery and various ventilation shafts.
But all of the above we know from history, but what about some lesser-known facts?
1—Did you know that base of the pyramid covers 55,000 m2 (592,000 ft 2) with each side greater than 20,000 m2 (218,000 ft2) in area? Incredible, right?
2—The interior of the Great Pyramid of Giza is another fascinating fact. The interior temperature is constant and equals the average temperature of the earth, 20 Degrees Celsius (68 Degrees Fahrenheit).
3—The outer mantle of the Great Pyramid of Gita is composed of no less than 144,000 casing stones, all of them highly polished and flat to an accuracy of 1/100th of an inch, about 100 inches thick and weighing approx. 15 tons each.
4—The Great Pyramid of Giza was once covered with amazing casting stones of highly polished limestone. These stones reflected the sun’s light and made the pyramid shine like a jewel. They are no longer present being used by Arabs to build mosques after an earthquake in the 14th century loosened many of them. It has been calculated that the original pyramid with its casing stones would act like gigantic mirrors and reflect light so powerful that it would be visible from space as a shining star on Earth.
5—The Ancient Egyptians referred to the Great Pyramid as Ikhet“, meaning the “Glorious Light.“
6—One of the most fascinating facts about the Great Pyramid of Giza is that it is the most accurately aligned structure in existence and faces true north with only 3/60th of a degree of error. The position of the North Pole moves over time, and the pyramid was exactly aligned at one time.
7—Oh and, it happens to be located at the center of the land mass of the earth. The east/west parallel that crosses the most land and the north/south meridian that passes the most land intersect in two places on the earth, one in the ocean and the other at the Great Pyramid.
8—It’s the most unique pyramid in the world, and it’s not because of its size, but because of its design. The four faces of the pyramid are slightly concave, the only pyramid to have been built this way.
9—It is the only known eight-sided Pyramid ever discovered. The centers of the four sides are indented with an extraordinary degree of precision forming the only 8-sided pyramid; this effect is not visible from the ground or from a distance but only from the air, and then only under the proper lighting conditions.
10—The weight of the pyramid is estimated at 5,955,000 tons. Multiplied by 10^8 gives a reasonable estimate of the Earth’s mass.
