🏛️ Introduction to the Pyramids of Giza

The Great Pyramids of Giza, one of the original Seven Wonders of the World, are the only ones still in existence today. While widely recognized, these were neither the first nor the only pyramids in ancient Egypt. Built as a complex for kings chosen by gods to serve on Earth and transition to deities in the afterlife, these structures included a pyramid, palace, and temples. The tombs inside were filled with necessities like furniture, food, and gold. The first pyramid was built 80 years before the Pyramid of Giza, with around a hundred pyramids constructed overall, though many were left unfinished due to the pharaohs’ lifespans.

🔧 Construction of the Great Pyramid of Giza

Pharaoh Khufu began the construction of the largest pyramid around 2575 BCE, requiring over 2 million limestone blocks, each weighing approximately 2.5 tons. The project demanded around-the-clock work, with 25,000 workers contributing from across Egypt. Contrary to popular belief, these workers were not enslaved but well-fed and housed. The pyramids' design aligned with compass points and symbolized the sun's rays. The construction site was symbolically placed on the west bank of the Nile, mirroring the setting sun with life’s end.

🦁 The Sphinx and Second Pyramid

The second Pyramid of Giza, built for Pharaoh Khafre, is smaller but notable for the famous noseless statue of the Sphinx. Originally adorned with a nose and painted in vibrant colors, the Sphinx has the body of a lion and the head of Khafre, serving as a guardian facing the sunrise. It is one of the world's oldest and largest statues, partially buried until the early 1800s.

🛠️ Methods and Materials for Pyramid Construction

Workers sourced stone blocks from nearby and from 8 miles away, using slick sand and water to transport them on sleds. Soft when mined, limestone hardened upon exposure, making shaping crucial to prevent structural collapse. The construction methods remain a mystery, with theories suggesting a ramp system. Polished limestone and a gleaming capstone adorned the pyramid, while the interior consisted mainly of solid stone.

🏗️ Interior Design and Chambers

The pyramid's interior has minimal open space with three main chambers. Throughout construction, a burial chamber was always ready in case of the pharaoh's death. The King's Chamber, the largest, lies at the pyramid's heart. Hieroglyphs can be found in nearby decorated tombs, depicting ancient Egyptian life. Many treasures and secret passages exist within, with modern scientists using robots and x-rays to explore. The pyramids remain a 5,000-year-old mystery.

Transcripts

consider the Great Pyramids one of the

original Seven Wonders of the World and

the only one that still exists today did

you know that the Pyramids of Giza

weren't the only pyramids out there and

they weren't even the first ones first

there were the pretty good pyramids but

they didn't catch on nah I made that up

back to the story in ancient Egypt it

was believed that kings were chosen by

gods to serve on Earth as their

mediators in the afterlife they were

expected to become Gods themselves the

pyramid complex was built to make sure

that the king had everything they might

need in the afterlife the complex

included the pyramid a palace and

temples the Tomb in the pyramid where

the King was buried was filled with many

things they might need like Furniture

food and gold

vessels actually the first pyramid had

been built 80 years before the first

Pyramid of Giza appeared overall there

were around hundred of them some weren't

finished though since the construction

took a while and not every Pharaoh lived

long enough to see the end of the

construction and now let's talk about

the construction itself the biggest of

the Pyramids of Giza is as tall as a 40

story building so how on Earth did they

manage to build a structure that massive

5,000 years ago long before machines and

other equipment appeared well let's

figure it out so pharoh k Fu ascended

the throne around 2575 BCE and his

Architects started the construction of

the oldest and biggest of the Pyramids

of Giza he figured that over 2 million

Limestone blocks had to be used to build

the Pyramid each weighing around 2 and

1/2 tons around the weight of a rhino

the architect wanted to finish the

construction in 20 years to make it

possible a stone had to be carried and

pushed into place every 4 minutes 24

hours a day 7 days a week and 365 days a

year except leap year so obviously a lot

of workers were needed to make it happen

many believe that it was enslaved people

who worked at the pyramids construction

site but that's not true workers came

from all over Egypt to contribute to the

project all in all around 25,000 of them

the Egyptians were doing all kinds of

work starting with manual labor and

crafting tools to administrative work

they all worked around 10 hours a day

they were housed and wellfed and they

were overall living a more comfortable

life than an average Egyptian could

afford at that time supposedly the

builders lived in a nearby temporary

City and were a highly organized

Community with a strong

leader the pyramids seem to be designed

to align with the points on a compass

and their sides symbolized the Rays of

the Sun but back at that time there were

no compasses ancient Egyptians figured

out out the directions themselves and

with amazing Precision to align the

pyramids they used two constellations

the construction site was arranged on

the West Bank of the Nile River this

also had a symbolic meaning just like

the sun sets in the West Life sets in

the west as

well the second Pyramid of Giza was for

kufu son Pharaoh kafer it's a bit

smaller but this one has the famous

noseless statue of the Sphinx of course

originally it had a nose I would tell

you what happened to it but it's still a

mystery and no one knows for

sure sphinxes have the body of a lion

and the head of a human they were

considered guardians of important areas

this famous Sphinx also pronounced

Sphinx has the head of pharaoh Coffer

and is guarding his pyramid facing the

sunrise the Sphinx is one of the biggest

and oldest statues in the world

originally it not only had a nose but

was also painted scientists have

discovered traces of the red color of

its face so most likely the Sphinx was

painted red there are also remains of

yellow and blue color on its body the

statue definitely wasn't boring till

around 1800 the Sphinx was buried up to

its shoulders until an adventurer with a

team of 160 men dug it

out but let's get back to the

construction the workers of course

needed stone blocks there were two main

places where people could get these

Stones One Source was close to the

construction site but that fossil lined

Yellow Stone was only suitable for the

pyramid's interior the Limestone blocks

for the exterior were hauled from 8 Mi

away on 30t Long sleds apparently it

wasn't too hard to pull them the sand

mixed with the right amount of water was

pretty slick and 10 people could move a

sled even with a rock weighing so much

surprisingly cutting off a block of

limestone wasn't the biggest problem

when in the ground it was soft and could

be split relatively easy but after

getting exposed to the air Limestone

hardens so the most difficult part was

to shape the blocks that step was

crucial because the smallest

inaccuracies could lead to the whole

pyramid collapsing so okay those

limestones were mined carried on a sled

shaped and then what how could they be

put into place well this is still a

mystery archaeologists have discovered

the remains of a ramp system that dates

back around the time the pyramids were

being built so historians have come to

the consensus that most likely the

Egyptians designed a unique ramp system

to move and pull huge stone blocks the

most common opinion is that there were

several ramps around the pyramid there

probably was a central ramp with two

staircases on each side of it built over

the pyramid Stones the ramp was growing

as the pyramid was getting higher people

might have been walking up the stairs

pulling up stones on wooden sleds but

this is just one of the options other

experts say that the ramps were around

the pyramid and some say that the ramps

were inside the pyramid maybe we will

never know for sure and it'll forever

remain a

mystery the exterior Limestone of the

pyramid was polished with Sand and Stone

until it gleamed on top there was a gold

and silver Capstone which glimmered over

Egypt like a second sun so that's how it

was 5,000 years ago now about the

interior surprisingly there's not much

inside the pyramid most of it is just

solid stone with very little open space

but let's take a quick look inside from

the entrance there are two stairways one

going down and the other going up they

take us to the chambers there are three

of them inside now why is that

apparently throughout the whole

construction a burial chamber had to be

prepared at all times just in case a

pharaoh kicked the bucket before the

construction ended so separate Chambers

were built one after another as the

construction progressed the last of them

was the main one it's called The King's

chamber it's the one where kufu was

resting it's the biggest room at the

very heart of the pyramid and there's a

big passageway leading to it it was

likely used as a kind of el elevator to

move Granite up to build the

interior Granite was also used to make

five stories of support beams to ensure

that the pyramid didn't collapse and we

can see that it worked since it's been

standing for centuries unfortunately

none of these Chambers have hieroglyphs

on the walls if you want to see the

writings you should go to the decorated

tombs near the pyramids those pieces of

art are depiction of ancient Egypt's

culture and daily life the texts allow

researchers to study their language and

grammar the treasures that once were in

the pyramids have been taken by people

there are also many secret tunnels and

passages inside the pyramids but even

today no one knows the whole plan of the

Interior scientists have been sending

little robots with cameras inside for

many years but there's still a lot we

don't know about the pyramids now

they're trying to use an x-ray to scan

the pyramids from the outside without

going inside so yeah ancient Egyptians

did create a mystery no one has been

able to crack for 5,000 years

already that's it for today so hey if

you pacified your curiosity then give

the video a like and share it with your

friends or if you want more just click
