Angkor, capital of the Khmer
Empire and the largest city in the world in the 13th century, was
rediscovered by the French in the 19th century. They encountered an
abandoned city whose fascinating ruins continue to move us today. Right now,
scientists of every nationality continue trying to reveal the mystery behind
the vanishing of this civilisation that dominated the region for centuries. Its
water network was the key to the power of its rule, but was also its Achilles’
heel.
