Uncover the secrets of ancient civilizations as NOVA journeys to an archaeological site where teams of experts use traditional techniques to test their hypotheses. Try out two possible designs for the canopy that once covered the Colosseum– one of them borrowed from ancient ships; and watch a band of experts move, raise and cap a structure like the mysterious Stonehenge–armed with only Stone Age tools.

Special DVD features include: materials and activities for educators, access to the NOVA Web site, scene selections and closed captions.
