How did they build the Great Pyramid of Giza? - Soraya Field Fiorio
TLDRThe video script details the construction of the Great Pyramid of Giza, built as the eternal resting place for Pharaoh Khufu around 2575 BCE. Architect Hemiunu, with a 20-year timeline, faced the monumental task of quarrying and transporting over 2 million limestone and granite stones, each weighing up to 80 tons. The pyramid's construction involved a complex logistical operation, utilizing a labor force of 25,000 workers who were well-fed and housed, contradicting the notion of enslaved labor. Innovative techniques included carving the bedrock plateau to form a level foundation and employing sleds made from cedar trunks to haul stones over long distances. The construction process remains a subject of debate, with limestone ramps being a consensus method for moving the massive stones. Three burial chambers were constructed, with the King's Chamber featuring a grand granite ceiling supported by strong granite beams. The pyramid was finished with a polished white limestone casing and a gleaming electrum capstone, symbolizing a second sun over Egypt. The video is sponsored by Marriott Hotels, celebrating the spirit of exploration and travel.
Takeaways
- 🏺 The Great Pyramid of Giza was built as the tomb for Pharaoh Khufu around 2575 BCE, and it remained the world's tallest manmade structure for over 3,800 years.
- 🏗 The architect, Hemiunu, estimated it would take 20 years to complete the pyramid and required a massive labor force of 25,000 workers.
- 👷 The laborers were not slaves but Egyptian citizens who were well-fed and housed, performing a variety of tasks from manual labor to administrative work.
- ⏳ The construction pace was intense, with one stone block quarried, transported, and set in place every 3 minutes, non-stop, to meet the 20-year timeline.
- 🛤️ A 6.5-kilometer canal was dug, and enormous amounts of limestone and granite were quarried to construct the pyramid.
- 🏔 The construction site was chosen on the west bank of the Nile due to the presence of a plateau of bedrock, which provided a stable foundation.
- 🔨 Limestone was quarried from two different sites, with the exterior stones coming from a quarry 13 kilometers away.
- 📐 Each stone used in the pyramid weighed up to 80 tons and had to be shaped with extreme precision to avoid structural failure.
- 🚜 Limestone ramps are believed to have been used for moving the stones into place, though the exact number and location of these ramps are still debated.
- 🛠️ Granite, stronger than limestone, was used for the pyramid's support beams and was quarried using dolerite rocks as hammers.
- 🏰 Three burial chambers were built during the construction, with the King's Chamber located at the pyramid's heart, featuring a grand granite ceiling.
- ✨ The pyramid was originally encased in polished white limestone and topped with a capstone made of electrum, which shined like a second sun over Egypt.
Q & A
When did Pharaoh Khufu ascend the throne and initiate the work on his pyramid?
-Pharaoh Khufu ascended the throne circa 2575 BCE, and work on his pyramid, his eternal resting place, began immediately.
Who was the architect responsible for designing the Great Pyramid?
-The architect of the Great Pyramid was Hemiunu.
How long did Hemiunu estimate it would take to complete the royal tomb?
-Hemiunu determined that it would take 20 years to finish constructing the royal tomb.
What was the significance of the Great Pyramid's height for an extended period?
-The Great Pyramid remained the world's tallest manmade structure for over 3,800 years.
What was the purpose of the 6-and-a-half-kilometer canal in the construction process?
-The canal was dug to facilitate the transportation of the enormous amounts of limestone and granite needed for the pyramid's construction.
Why was the west bank of the Nile chosen as the construction site for the pyramid?
-The west bank of the Nile was chosen because Egyptians associated death with the west, like the setting sun, and the plateau of bedrock there could better support the pyramid's weight than shifting sand.
How did masons save time during the construction of the pyramid?
-Masons carved the plateau itself to resemble the stones used for the rest of the pyramid, creating a level foundation that allowed construction to begin immediately.
What was the size of the workforce required for the pyramid project?
-The project required a staggering 25,000 workers.
How were the workers involved in the pyramid's construction treated?
-Contrary to popular belief, the workers were not enslaved. They were housed and fed with rations better than the average Egyptian could afford.
What was the pace of construction to meet the 20-year deadline?
-To complete the project in 20 years, one block of stone had to be quarried, transported, and put into place every 3 minutes, 365 days a year.
How were the stones for the pyramid's exterior transported?
-The stones for the exterior were hauled from roughly 13 kilometers away using 9-meter long sleds made from giant cedar trunks.
What material was used for the pyramid's capstone and why was it significant?
-The capstone was covered with electrum, which glimmered like gold, making it shine like a second sun over all of Egypt, symbolizing the pharaoh's divine status.

🏺 The Construction of the Great Pyramid of Giza
The script details the monumental efforts undertaken by Pharaoh Khufu's architect, Hemiunu, to build the Great Pyramid circa 2575 BCE. It took 20 years to complete this tomb, which remained the world's tallest manmade structure for over 3,800 years. The construction process involved digging a 6.5-kilometer canal, quarrying vast amounts of limestone and granite, and using kilometers of rope to move the stones. The exact methods are still debated, but it's known that a construction site on the west bank of the Nile was chosen due to its stable bedrock. Masons carved the plateau to resemble the pyramid's stones, and the project employed 25,000 workers from across Egypt who were well housed and fed. The workers' tasks varied from crafting tools to manual labor. The construction pace was intense, requiring one stone block to be quarried and set every 3 minutes. Limestone was sourced from two quarries; the closer one provided stone for the interior, while the exterior stones were brought from 13 kilometers away using sleds made from cedar trunks. The limestone was shaped using wooden mallets and copper chisels, and the pyramid utilized over 2 million stones, each weighing up to 80 tons. The construction also included three burial chambers, with the King's Chamber being a significant feature located at the pyramid's heart. Granite, stronger than limestone, was used for support beams and had to be quarried with dolerite hammers. The pyramid was eventually encased in white limestone and topped with a capstone of electrum, symbolizing a second sun over Egypt.
