How it arose like a beacon from the ashes of the older church, the scale of its ambition posing seemingly impossible engineering challenges.

But behind this triumph of engineering lies a dark story of violence, political double-dealing and destruction.
The Great Pyramid
The Great Pyramid of Giza is four-and-half thousand years old. It's the only ancient Wonder of the World still standing. It was conceived as a resurrection machine for the enigmatic pharaoh Khufu in 2551 BC and completed over 20 years later, just before his death. To cut and move the 2 million stones needed to build it would involve the organisation of the whole Egyptian state.
