There are more than 1,000 temples in Angkor which have been reclaimed from the jungle and some are magnificent architectural gems to rival the best around the world. <br />Recent Satellite photos have revealed that Angkor spread over 400 square miles making it the largest preindustrial center in the world. <br />Here are some of the best. <br />The immense Khmer empire from the 9th to the 15th C century stretched over present day Cambodia, Thailand, Laos, Vietnam all the way to India. At Angkor it created a sophisticated network of hydraulic canals and rice paddies that supported over a million people and left architectural monuments that are as overwhelming as ancient Egypt. <br />The ruins of Angkor have been declared a Unesco World Heritage site. <br />In 1431 enemy armies invaded and sacked Angkor. The population left , the region was abandoned and most of this incredible culture was swallowed up by the jungle.
