At 146.5 m (481 ft) high, the Great Pyramid stood as the tallest structure in the world for more than 4,000 years. Today it stands at 137 m (449.5 ft) high, having lost 9.5 m (31 ft) from the top. Here's how the Great Pyramid compares to some modern structures.

For roughly 3,800 to 4,000 years, the Great Pyramid of Giza in Egypt held the undisputed title of the tallest man-made structure in the world. Completed around 2560 BC as a tomb for the Pharaoh Khufu, it originally stood at a height of approximately 146.6 meters (481 feet), though erosion and the loss of its smooth limestone casing have reduced it to about 138 meters today. Its record-breaking reign was so long that it remained the tallest structure through the rise and fall of the Roman Empire, the Middle Ages, and the height of the Mayan civilization. Its title was finally overtaken in 1311 AD by the central spire of Lincoln Cathedral in England, which reached an estimated height of 160 meters (525 feet). The cathedral held the record for over two centuries until its spire collapsed during a storm in 1548. The Great Pyramid remains the only one of the Seven Wonders of the Ancient World still largely intact, serving as a testament to the incredible engineering capabilities of the ancient Egyptians.
