9The Great Pyramid of Giza, Egypt
The Great Pyramid of Giza, also known as the Pyramid of Khufu, stands as the last of the Seven Wonders of the Ancient World still largely intact. Constructed around 2580-2560 BCE during the Fourth Dynasty of the Old Kingdom, this colossal structure originally stood at 146.6 meters (481 feet) tall. Built with an estimated 2.3 million blocks of stone, each weighing between 2.5 and 15 tons, the pyramid served as a tomb for the Pharaoh Khufu. Its precise alignment with the cardinal points and its complex internal structure reflect the advanced engineering and astronomical knowledge of ancient Egypt.
