The Great Pyramid of Giza, built approximately 4,500 years ago in Egypt, continues to astound and inspire curiosity in people worldwide. Rising to a height of 147 meters, it held the title of the tallest man-made structure for over 4,000 years, a record unmatched until the construction of medieval cathedrals like Lincoln Cathedral in 1311 AD. Constructed with an estimated weight of 6 million tonnes of heavy stones, it dwarfs modern engineering marvels like the Burj Khalifa, which weighs a mere 500,000 tonnes.
How did ancient Egyptians, without cranes, bulldozers, or even wheels, achieve such a monumental feat? By employing innovative techniques and tools such as copper chisels, dolerite hammers, and wooden sledges to carve, transport, and position stones, they overcame these challenges with remarkable ingenuity. Let’s explore the mysteries surrounding this architectural marvel.

Historical Context
The Great Pyramid is believed to have been constructed around 2560 BC under Pharaoh Khufu, the second monarch of the Fourth Dynasty of Egypt’s Old Kingdom. Despite debates about the exact duration of his reign—ranging from 23 to over 60 years—Khufu’s legacy is immortalized in this colossal structure. The pyramid is part of the Giza Plateau, located on the west bank of the Nile River.
It is one of three main pyramids at the site, accompanied by the Pyramid of Khafre and the smaller Pyramid of Menkaure, believed to be built by Khufu’s son and grandson, respectively. The site also includes the Great Sphinx, burial tombs, and smaller pyramids, showcasing ancient Egypt’s grandeur.
Purpose of the Pyramids
The pyramids were constructed as tombs for the Pharaohs, reflecting their deep-seated belief in an eternal afterlife—a concept that permeated Egyptian culture, influencing art, religious practices, and the architectural grandeur seen in other monuments such as temples and burial sites. Ancient Egyptians held that life did not end with death; instead, the soul journeyed to the underworld to be judged by the gods.
A lavish tomb filled with treasures, food, and everyday items was thought to ensure a comfortable afterlife. Pharaohs’ mummified bodies were placed in sarcophagi within the pyramids. Although archaeologists found an empty sarcophagus in the Great Pyramid of Giza, no treasures were discovered, leading to speculation that it was looted long before modern explorers arrived.
Myths and Conspiracy Theories
The lack of definitive evidence about the Great Pyramid’s construction has spawned numerous theories, partly because its enigmatic nature invites speculation. These myths and theories persist despite archaeologists’ discoveries, fueled by popular fascination with the unknown, cultural narratives, and sometimes a lack of widespread understanding of the historical and scientific evidence.
Some claim it was a power plant capable of generating electricity, citing ancient artworks allegedly depicting light bulbs. Others, like American politician Ben Carson, theorized that it was a granary built by biblical figures. These ideas lack substantial evidence and are largely dismissed by historians and archaeologists. The consensus remains that the pyramid was constructed as a tomb.
Construction Techniques
One of the most intriguing aspects of the Great Pyramid is how it was built. Contrary to popular depictions of slave labor, archaeological evidence suggests that highly skilled workers constructed the pyramid.
These workers, numbering 20,000 to 30,000, were well-fed and housed in nearby communities. Farmers often joined the workforce during the agricultural off-season, contributing to this national project.
Stone Cutting and Transport
The pyramid’s construction required 5.5 million tonnes of limestone, 8,000 tonnes of granite, and 500,000 tonnes of mortar. Stones were quarried using copper tools and broken with dolerite, a harder rock. Wooden wedges soaked in water were inserted into cracks to break the stones apart.
The stones were then transported via rafts on the Nile and pulled to the site using sledges on wet sand, as suggested by a 2014 study. The wet sand reduced friction, making it easier to move heavy loads.
Lifting and Stacking Stones
How these massive stones were lifted and stacked remains a mystery. Archaeologists propose that ramps—straight, zigzag, or circular—were used. A wooden ramp system uncovered in 2015 supports this theory. Levers and counterweights may also have been employed, similar to the Shadoof mechanism used to draw water from the Nile.
Architectural Precision
The pyramid’s design demonstrates an astonishing level of precision, achieved through methods such as aligning its sides with the cardinal directions using celestial observations and employing tools like plumb bobs and leveling instruments for accuracy. Its sides align almost perfectly with the cardinal directions, with an error of just one-fifteenth of a degree.
This alignment could have been achieved by observing the autumn equinox or using the stars, though theories like the Orion Correlation Theory, which suggests alignment with the stars in Orion’s Belt, remain controversial.
Enduring Legacy
The outer casing of the Great Pyramid, made of fine white limestone, once gleamed brilliantly under the sun. Though much of it has eroded over millennia, the pyramid’s core structure remains intact, a testament to ancient Egyptian engineering. Despite numerous earthquakes and centuries of weathering, the pyramid still stands as a symbol of resilience and ingenuity.
