If you have visted the temple ruins at Angkor, would like to expand your understanding of history, or maybe you are just a Laura Kroft:  Tomb Raider fan, you will enjoy the new National Geographic TV Secrets of Angkor.   Archaeologist, with the help of aerial and satellite imagery, and braving landmines on foot, are finding a vast new city and waterworks system that surrounds the moated area that travelers typically see.  The discoveries are leading them to conclude that:

“Angkor was the world’s largest pre-industrial city, growing to an area of about 390 square miles.” 

“Covering an area larger than modern-day New York, ancient Angkor has been estimated to have had a population of 750,000 people at its height in the 12th or 13th century.”
