Mystery surrounding Angkor Wat's massive stone finally solved

London: Archaeologists have uncovered traces of a series of canal, which suggest that the 5 million tonnes of sandstone used to build Cambodia's Angkor Wat took a far shorter route than previously thought.

The sandstone blocks each weigh up to 1.5 tonnes and originate from quarries at Mount Kulen, New Scientist reported.

Earlier it was assumed they were taken 35 kilometres along a canal to Tonle Sap Lake, rafted another 35 km along the lake, then taken up the Siem Reap River for 15 km, against the current.

Etsuo Uchida and Ichita Shimoda of Waseda University in Tokyo, Japan, were sceptical about this theory, so they used satellite images to search for a shortcut.

And they discovered canals leading from the foot of Mount Kulen to Angkor - a gentle 34-km route, as opposed to the arduous 90-km trek previously suggested.

The pair also uncovered more than 50 quarries at the foot of Mount Kulen and along the route. The stones they found matched those in the temples, as reported in the Journal of Archaeological Science.

Uchida believes all the stone used for the monuments was probably transported along these canals.

Mitch Hendrickson of the University of Illinois, Chicago, says Uchida's theory could be confirmed by searching for blocks that fell overboard into the canals.

He believes the canals were used for several purposes, including the transportation of important minerals such as iron.
