Ancient Drains Back In Use After 2300 Years

* The old drainage system in Pompeii is so strong that it can still be re-activated following its completion almost 2,300 years ago. An area of 1500ft stretch of tunnels underneath some of the famed Italian city’s most iconic structures was originally built to drain water downhill away from Pompeii’s center. Tunnel analysis showed that for centuries it had almost remained untouched and the complex system still exists in good shape. __________________________________ * Narrations belong to Blast World Mysteries * Edited and Animated by : Blast World Mysteries * Second Channel : https://www.youtube.com/channel/UCN0UO-xj7nWFk7gpcZ2USdA
