Airborne laser reveals hidden city in Cambodia
SYDNEY (AP) Airborne laser technology has uncovered a network of roadways and canals, illustrating a bustling ancient city linking Cambodia's famed Angkor Wat temple complex.
The discovery was announced late Monday in a peer-reviewed paper released early by the journal Proceedings of the National Academy of Sciences. The laser scanning revealed a previously undocumented formally planned urban landscape integrating the 1,200-year-old temples.
The Angkor temple complex, Cambodia's top tourist destination and one of Asia's most famous landmarks, was constructed in the 12th century during the mighty Khmer empire. Angkor Wat is a point of deep pride for Cambodians, appearing on the national flag, and was named a UNESCO World Heritage Site.
Archaeologists had long suspected that the city of Mahendraparvata lay hidden beneath a canopy of dense vegetation atop Phnom Kulen mountain in Siem Reap province. But the airborne lasers produced the first detailed map of a vast cityscape, including highways and previously undiscovered temples.
