Lost Worlds investigates the very latest archaeological finds at three remote and hugely significant sites - Angkor Wat, Troy and Persepolis.

Lost Worlds travels to each site and through high-end computer graphics, lavish re-enactment and the latest archaeological evidence brings them to stunning televisual life. From the 900-year-old remains of Angkor Wat in the Cambodian jungle the staggering City of the God Kings is recreated. From Project Troia, in North West Turkey, the location of the biggest archaeological expedition ever mounted the lost city is stunningly visualised and finally from Persepolis the city and the great Persian Empire are brought to life.
