Longest Underground Aqueduct in the World Discovered

When they were not too busy conquering distant lands, the Romans liked to dig. German hydromechanics professor Mathias Döring discovered that Roman engineers spent a century digging a 66-miles long underground aqueduct to bring water to modern day Syria:

The soldiers chiseled over 600,000 cubic meters of stone from the ground — or the equivalent of one-quarter of the Great Pyramid of Cheops.

“Over the first 60 kilometers, the tunnel has a gradient of 0.3 per thousand,” explains the project director. That works out to 30 centimeters per kilometer — an astonishingly shallow angle of descent.
