Discover the world's largest empire in Cambodia

Archaeologists have discovered many ancient strongholds near Cambodia's Angkor Wat ruins, according to The Guardian.

Thanks to Lidar technology (remote surveying with laser scanners), the team of Australian expert Damian Evans discovered the remnants of medieval buildings of large citadel built way away. here 900 - 1,400 years. A few of them have large areas across Phnom Penh.

The results of this study will be published in the Journal of Archaelogical Science on June 13. If the hypotheses from these surveys are confirmed, this is the largest empire in the world in the 12th century.

A few of them have large areas across Phnom Penh.

Mr. Evans's group began the research process many years ago, but new findings show that the ancient citadel buildings are much larger than what experts once imagined.

"In 2012, we found ancient cities over time that had been completely covered by dense forests and no longer known, like Preah Khan citadel in Kompong Svay and Mahendraparvata in Phnom Kulen," Evans said.

Thanks to the findings in 2012, the team of experts has asked for additional funding to continue searching for mountain forests near Ankor Wat.

This time, a helicopter fitted with Lidar devices had obtained unexpected results. According to Mr. Evans, archaeologists have always argued that in the Middle Ages, prominent buildings like Angkor Wat were surrounded by a big city. Thanks to Lidar technology, they verified this assertion through "incredibly detailed" images .

Even the discovered relics such as Preah Khan (pictured), Mahendraparvata, new images also reveal many more things. At Mahendraparvata, experts recognized countless new temples, dams, lakes, roads . New discoveries could also alter many previous theories about the Khmer empire.
