Nothing represents the unique advanced civilization of ancient Egypt more than the pyramids. Much about them is still a mystery to researchers. Episode 5 of ANCIENT EGYPT – Chronicles of an Empire traces the history of Egyptian tomb architecture. We show how Egyptian tomb architecture evolved over the millennia. The journey begins about 5,000 years ago with the royal tombs in Abydos, where the first rulers of Egypt were buried in underground complexes.They are covered by a mound of earth, from which mastabas develop - impressive brick buildings. The climax of this development is the construction of the Pyramid of Khufu 4,500 years ago. With their pyramids, the Egyptians created monuments for eternity - and in the end, they actually became immortal.
