The historical structure built as a tomb for the Egyptian pharaohs is the Great Pyramid of Giza. Constructed around 2580–2560 BC during the Fourth Dynasty of the Old Kingdom, it is one of the most remarkable architectural feats of ancient times. Initially a tomb for Pharaoh Khufu, the pyramid was originally about 146.6 meters tall, making it the tallest man-made structure for millennia. It was built using limestone and granite, showcasing advanced engineering and labor organization. The Great Pyramid, part of a larger complex that includes the Sphinx, represents the Egyptians' beliefs about the afterlife and the pharaoh's role as a divine ruler.
