How long did the Great Pyramid of Giza hold the record as the tallest man-made structure in the world?

The Great Pyramid of Giza held the record as the tallest man-made structure in the world for an estimated 3,800 years. It was completed in the early 25th century BCE during the reign of Pharaoh Khufu. Originally standing at approximately 482 feet (147 meters), its height has been reduced to 449 feet (137 meters) due to erosion and the removal of its casing stones. The Great Pyramid was surpassed in height by modern skyscrapers in the late 19th and 20th centuries, such as the Eiffel Tower.123
