Uncover the secrets of ancient civilizations as NOVA journeys to five archaeological sites where teams of experts use traditional techniques to test their hypotheses. Stonehenge watches a band of experts move, raise and cap a structure like the mysterious Stonehenge-- armed with Stone Age tools. Inca explores magnificent mountainside citadels-- and marvels as villagers create a 150-foot suspension bridge using nothing but grass. Obelisk faces the challenge of quarrying, chiseling, hauling and mounting an obelisk--- using stones, ropes, logs and dirt. Colosseum tries out two possible designs for the canopy that once covered the Colosseum-- one of them borrowed from ancient ships. Pyramid joins the race to erect an 18-foot stone pyramid in three weeks-- while testing out some clever construction theories.
