The ancient culture credited with constructing the first known pyramids is the ancient Egyptian civilization. Around 2700 BCE, during the Third Dynasty, the Egyptians began building step pyramids, with the Pyramid of Djoser at Saqqara being one of the most notable examples. This initial form of pyramid evolved into the true pyramids that we associate with Egypt today, such as the Great Pyramid of Giza. These monumental structures not only served as elaborate tombs for pharaohs but also reflected the Egyptians' advanced understanding of engineering and their deeply held beliefs about the afterlife, showcasing their sophisticated culture and technological prowess.
