The ancient structure that is one of the Seven Wonders of the Ancient World is the Great Pyramid of Giza. Built around 2580–2560 BC as a tomb for the Pharaoh Khufu, it is the oldest and largest of the three pyramids on the Giza plateau in Egypt and the only wonder still largely intact. The Great Pyramid was originally covered in casing stones that reflected sunlight, making it shine brightly. It stood as the tallest man-made structure in the world for over 3,800 years and continues to draw millions of tourists, historians, and archaeologists fascinated by its grandeur and engineering prowess.
