There's no doubt that the ancient Egyptian pyramids are among the most profound achievements in the history of architecture. As one of the first civilizations in prehistory, the ancient Egyptians had made many advancements which formed a cornerstone of many following architectural achievements of other societies.
Egyptian architecture dates back around 2800 BC, which is five thousand years ago. Through dynasties or periods in Egyptian history, almost every pharaoh contributed to the development of architecture in Egypt. In fact, the pyramids of Egypt were built to contain the pharaoh and his family and belongings after their deaths. It was after a process of embalmment for preserving the bodies of pharaoh that the bodies were buried within the pyramids for eternal preservation.
Archaeologists have found within the ruins of some pyramids the consistent Egyptian writing we call hieroglyphics. From this, hieroglyphics were used as decoration as well as records of historic events. This feature of Egyptian architecture provides us with enormous information about Egyptian culture and society. This is how architecture impacts ancient society and even affects the modern world.
As soon as a pharaoh came to power work had begun on his pyramid. By the time his rule ended and he was succeeded, the pharaoh's tomb would have been complete, but the entire pyramids took years and years and more years to complete.
The best known complex of pyramids are the Great Pyramids at Giza, in particular - the Pyramid of Khufu or the Great Pyramid. Originally, this structure stood 480 feet high while each base was 756 feet long. In total there were about 2.3 million blocks that composed the pyramid and each weighed 2.5 metric tons!
As one of the seven wonders of the ancient world, it still remains a wonder how the ancient Egyptians were able to construct such a massive structure. This civilizations was one of the first and respectfully, one the most primitive. They did not widely used the wheel, which would have made construction quite easier. The only method modern archeologists can perceive is the use of pulleys and ramps. Still, how did they manage to "push" 2.3 million blocks, each weighing 2.5 metric tons, to complete the pyramids?
The size of the structures aren't their only magnificent aspect. The Egyptians also put much work, thought, and planning into their constructions. For instance, they made wide use of isosceles triangles. Much of the faces of the pyramids were at precise base angles and vertex angles. Many of the construction methods used by Ancient Egyptians we use today.
Another example is the Pythagorean Theorem: "A squared plus B squared equals C squared." The names is Greek because the Greeks introduced the concept into society widespread. the concept, however, was previously used by the Egyptians as well. As a result, the Egyptians not only contributed to modern architecture, but encompassed geometry and mathematics into Our World of Architecture.
