3. Norias of Hama
A noria is an ancient machine designed to use the natural flow of a river to lift water into an aqueduct. The Norias of Hama are among the most famous and, until a few years ago, some of the best preserved in the world. In 2014, it was revealed that the norias had been willfully destroyed by mortar rounds, reportedly by pro-Assad forces. Additionally, much of the surrounding historic city of Hama was extensively damaged during various skirmishes.
