A thousand years ago the Khmer people of Cambodia built an empire that stretched a million square kilometers. It became the largest superpower the region has ever seen. Their capital was the great city of Angkor, once the largest city on Earth. Its centerpiece was Angkor Wat - a vast temple complex covering an area more than four times the size of Vatican City

Buried in the Cambodian jungle lie the lost remains of the great medieval city of Angkor, once the capital of one of the world\\\'s greatest civilisations. Today, only the great stone temples like Angkor Wat survive. But Angkor was once a teeming metropolis, full of life - the biggest city on Earth.
