The structure considered one of the ancient Seven Wonders of the World is the Great Pyramid of Giza. Located near Cairo, Egypt, it is the only remaining wonder from the original seven. Built around 2580-2560 BC during the Fourth Dynasty of the Old Kingdom, the Great Pyramid served as a tomb for Pharaoh Khufu. Constructed from limestone and granite, it originally stood at approximately 147 meters (481 feet) tall. Its precise construction and immense scale continue to astound historians and archaeologists, making it an enduring symbol of ancient engineering and civilization.
