Perhaps one of the greatest technological feats of the early Persian
civilization was the Shushtar Historical Hydraulic System. This highly
complex system has been referred to as "a masterpiece of creative
genius" and declared a world heritage site by UNESCO (United Nations
Educational, Scientific, and Cultural Organization). This historical
site is probably best described as a hydraulic super factory! Its
infrastructure is made up of watermills, dams, tunnels, canals, pools,
and waterfalls and at one time powered up to 40 watermills in the
surrounding area. What makes Shushtar so advanced and unique was that
several cultures have helped advance it through out the ages from the
early Persians, Romans, all the way back to Darius The Great, an
Achaemenian king of Iran. This remains to be seen as one of the greatest
exchanges of hydraulic engineering and its application throughout
antiquity.
