Petra: Lost City of Stone

NOVA: For over a millennium, Petra was lost to the Western world and less than one per cent of the city has been explored in the 200 years since its rediscovery. An archaeologist and a team of sculptors carve a temple-tomb to find out how the people of Petra built their city of stone. Also, scientists in modern-day Jordan use remote sensors and hydraulic flumes to discover a city of the living, complete with a water system that supplied 30,000 people with drinking water, fountains and bathhouses.
