The ancient structure considered one of the Seven Wonders of the Ancient World is the Great Pyramid of Giza. Located in Egypt, it is the largest and oldest of the three pyramids on the Giza plateau and was built as a tomb for the Pharaoh Khufu around 2580–2560 BC. Remarkably, the Great Pyramid originally stood about 146.6 meters (481 feet) tall and was constructed from an estimated 2.3 million stone blocks. Its incredible engineering and construction techniques have fascinated historians and archaeologists for centuries, making it a symbol of ancient innovation and human achievement, surviving over 4,500 years.
