BBC - Jungle Atlantis (2014) Part 2 Death of Angkor Wat's Megacity

Jungle Atlantis

Millions of tourists visit Angkor Wat in Cambodia every year to marvel at its remarkable architecture, yet most are probably unaware that when it was built nearly 1,000 years ago it was even more impressive.

Using remote sensing technology, scientists now know what is hidden beneath the nearby paddy fields and jungle: a sophisticated metropolis with an elaborate network of houses, canals, boulevards and temples covering 30 square kilometres that housed three-quarters of a million people. To put that into perspective, London at that time was home to just 18,000.

Part 2: Death of Angkor Wat's Megacity

Part two of two. The experts continue their attempt to discover why Angkor suddenly collapsed, using a revolutionary technology called LiDAR to reveal the true scale and splendour of this abandoned megacity. Deep in the Cambodian jungle, they have discovered a sophisticated network of roads and canals that are the forgotten world of Angkor's greatest king, shedding new light on the dramatic events leading to the fall of the city.
