tomb.

Why did the Pharaoh build the pyramids?

How were the huge pyramids built?

Some people say that the pyramids were created by aliens. What is the truth?

According to legend, before the Third Dynasty of ancient Egypt, both princes, ministers and common people were buried in a rectangular tomb made of mud bricks. The ancient Egyptians called it "mastaba".

Later, a smart young man named Imhotep invented a new construction method when designing a tomb for the Egyptian Pharaoh King Djoser.

He used square stones quarried from the mountain instead of mud bricks, and continued to modify the design of the tomb. Finally, he built a six-level trapezoidal pyramid - this is the prototype of the pyramid we see now.

In ancient Egyptian literature, the pyramid was layered in a trapezoidal shape, so it was also called a hierarchical pyramid.

This is a tall pyramidal building with a square base and a triangle on each side. It looks like the Chinese character "金", so we call it "pyramid".

The tower-style mausoleum designed by Imhotep was the first stone mausoleum in Egyptian history.
