Mystery of the Great Pyramid

S1 E4: In ancient Egypt, workers are racing to finish the largest pyramid on the planet for their pharaoh, Khufu. But time is running out. The purpose of this giant tomb is to transport the king to the afterlife; if it's not completed when he dies, his dreams of immortality could be dashed. Witness the final construction phase of the Great Pyramid of Giza and what it looked like 4,500 years ago. Then see how the recent discovery of an ancient papyrus has rewritten history and changed our understanding of just how this massive monument was built.
