In September 2002 an extraordinary event happened at the Great Pyramid of Giza –the biggest, the grandest, the most mysterious of all the pyramids of Ancient Egypt. Teams of archaeologists and engineers were conducting two remarkable explorations –whilst the whole thing was also broadcast live on television. In the ancient cemetery of the pyramid builders the oldest sealed coffin ever found in Egypt would be opened. It was thought to belong to the most important overseer of the whole pyramid project. At the same time an exploration was underway deep inside the Great Pyramid. A robot crawled up a secret shaft to see what lay beyond a mysterious door. New spaces in the pyramid discovered by the robot, would help Egyptologists understand the purpose of the pyramid itself.
