S1, E2: Twenty-five hundred years before the reign of Julius Caesar, the ancient Egyptians were deftly harnessing the power of engineering on an unprecedented scale. Egyptian temples, fortresses, pyramids and palaces forever redefined the limits of architectural possibility. They also served as a warning to all of Egypt's enemies-that the world's most advanced civilization could accomplish anything. This two-hour special uses cinematic recreations and cutting-edge CGI to profile the greatest engineering achievements of ancient Egypt, and the pharaohs and architects who were behind them. Includes Djoser's Step Pyramid at Saqqara, Senusret's Nubian Superfortresses, Hatshepsut's Mortuary Temple at Dier el-Bahari, Akhenaten's city at Amarna, and the temples of Ramesses the Great at Abu Simbel.
