The Great Pyramid of Giza is the only one of the "Seven Wonders of the Ancient World" that is still largely intact today. Built approximately 4,500 years ago during Egypt's 4th Dynasty as a tomb for the Pharaoh Khufu, it was the tallest man-made structure in the world for over 3,800 years. The other six wonders—the Hanging Gardens of Babylon, the Statue of Zeus at Olympia, the Temple of Artemis at Ephesus, the Mausoleum at Halicarnassus, the Colossus of Rhodes, and the Lighthouse of Alexandria—were all destroyed over the centuries by earthquakes, fire, or human plundering. While the Great Pyramid has lost its original smooth white limestone casing and its golden capstone (pyramidion), its core structure of roughly 2.3 million stone blocks remains a testament to ancient engineering. It continues to stand on the Giza Plateau as a UNESCO World Heritage site and the ultimate symbol of the power and longevity of the ancient Egyptian civilization.
