The ancient civilization that built the pyramids is the Egyptians, specifically during the era of the Old and Middle Kingdoms around 2600 to 1800 BC. The most famous pyramids, including the Great Pyramid of Giza, were constructed as tombs for pharaohs and are indicative of the Egyptians’ advanced architectural skills and understanding of mathematics. These monumental structures not only served religious purposes but also demonstrated the wealth and power of ancient Egyptian society. Today, the pyramids are recognized as one of the Seven Wonders of the Ancient World and remain a significant symbol of ancient engineering and culture.
