Over 4,500 years ago, the Great Pyramid of Giza was built using more than 2.3 million stone blocks, each weighing up to 80 tons. Standing once at 146.6 meters (481 feet) tall, it remains one of the greatest mysteries on Earth. But why was it built? And what secrets are still hidden inside?
The Great Pyramid of Giza is one of the most famous structures in the world. It’s also one of the most mysterious. It still amazes scientists, engineers, and regular people like us.
Many of you wonder:
- Why is it a mystery how the pyramids were built?
- How old is the pyramid of Giza?
- How tall is the pyramid of Giza?
- Is there a secret room in the Great Pyramid?
When Was the Great Pyramid of Giza Built?
The pyramid was built around 2600 BCE, during Egypt’s Fourth Dynasty. It was made for Pharaoh Khufu (also called Cheops).
- 📍 Location: Giza Plateau, near Cairo
- ⏳ Time to build: Around 20 years
- 🧱 Material: Limestone, granite, and mortar
- 🛠️ Architect (believed): Hemiunu, Khufu’s relative and top engineer
How Was the Pyramid Built? Still a Mystery?
One of the biggest questions is: “How were the pyramids built?”
Without machines or modern tools, building such a huge structure seems almost impossible. But the Egyptians were smart engineers.
🧱 Block Size and Weight
- Around 20,000–30,000 workers
- They weren’t slaves — they were skilled workers, well-fed, and respected
- They worked in shifts, likely 3 months at a time
- Average weight: 2.5 tons (5,000 pounds)
- Heaviest blocks: 50–80 tons
- Total number of blocks: About 2.3 million
Here’s how the block size changes from bottom to top:
Dimensions: Big, Precise, and Full of Math
Let’s take a look at the pyramid’s exact measurements:
Feature | Measurement |
Original Height | 146.6 meters (481 ft) |
Current Height | 138.5 meters (454 ft) |
Base Length | 230.33 meters (756 ft) |
Volume | 2.6 million m³ |
Slope Angle | 51°50′40″ |
Weight | 5.75 million tons |
Here’s a visual of how the height changed over time:
🔢 Mathematical Secrets
The pyramid isn’t just big—it hides math puzzles:
Perimeter ÷ Height ≈ 2π
Uses the Golden Ratio (Φ) and Euler's Number (e)
Built with a Seked of 5½ palms (an old Egyptian measurement for slope)
What Is Hidden in Giza?
Beneath the Giza Plateau lies a vast subterranean world. Ground-penetrating radar has shown:
- 2 km wide systems
- As deep as the Eiffel Tower (about 300 meters)
- Chambers and passages not yet explored
🔍 ScanPyramids Project (Started in 2015)
Using cosmic-ray scans, scientists found:
- A hidden corridor (30 ft long) behind the main entrance
- A giant void above the Grand Gallery (98 ft long)
- Possible secret rooms that were never opened
Exploring the Inside: Rooms and Passages
Here are some key parts of the pyramid and how long they are:
Part of Pyramid | Length |
Ascending Passage | 29.7 m |
Grand Gallery | 46 m |
Subterranean Chamber (depth) | 27 m |
Hidden Corridor (new) | 9.14 m |
King’s Chamber Passage | 45 m |
Queen’s Passage | 2 m (approx) |
🏛️ King’s Chamber
- Made of red granite
- Includes five relieving chambers above to prevent collapse
- Air shafts aligned with stars
🏛️ Queen’s Chamber
- Contains a niche, possibly for a statue
- Damaged by treasure hunters
🔦 The Secret Room in the Great Pyramid?
- The secret void discovered above the Grand Gallery is massive
- Its purpose is still unknown — maybe a chamber or pressure release?
- More exploration is needed to confirm its role

The Great Pyramid isn’t just made of stone — it’s built with mystery. Over the years, many filmmakers and scientists have teamed up to create documentaries that explore the dark secrets of the pyramid, its purpose, and what might still be hidden inside.
Let’s explore some of the most exciting ones that bring these ancient wonders to life:
1. Decoding the Great Pyramid (PBS NOVA, 2019)
What if we told you that archaeologists have finally figured out how ancient Egyptians moved 80-ton stones without machines? This documentary follows the latest discoveries that give us a clear, practical look at how the pyramid may have been built using ramps, tools, and smart teamwork.
2. Secrets of Giza (2020)
Led by world-famous Egyptologist Zahi Hawass, this film uncovers the deep secrets buried beneath the sands of Giza. From hidden tombs to strange architectural clues, it takes you on a journey through one of the most mysterious places on Earth.
3. The Pyramid Code (2009)
This series doesn’t just ask how the pyramids were built — it asks why. Could the pyramids hold spiritual energy? Were they connected to the stars? Could ancient Egyptians have been more advanced than we think?
4. Egypt’s Secret Pyramids: Solving the Mystery (2023)
With high-quality CGI and satellite scans, this documentary lets you see inside the pyramids without even going to Egypt. It shows how the stones were placed, what hidden spaces exist, and how modern tech is finally catching up with ancient genius.
5. Unknown: The Lost Pyramid (Netflix, 2023)
Join real archaeologists in the desert as they hunt for a missing pyramid and explore tombs that haven’t been touched in thousands of years. It’s like Indiana Jones — but real.
These documentaries aren’t just about watching stones and sand. They’re about exploring the truth behind one of the world’s oldest and greatest mysteries, the secrets of the Great Pyramid of Giza.
While not all theories are proven, they still make us wonder:
"Why is it a mystery how the pyramids were built?"
Because even today, we can’t fully recreate them with the same precision!
