Dehistan
Looking at the smooth, barren plain of the Misrian plateau, which is part of the South-East Caspian Sea, it is difficult to imagine that once it was the blooming, fertile oasis. But when viewed from the above, in the light of rays of the rising sun, on the relief of this area there will be clearly seen traces of ancient irrigation: channels' beds, squares of irrigated fields, where, according to researchers, a variety of crops - from wheat to rice - were grown. The researchers have already gathered sufficient evidence proving that the lands of Dehistan were used for about three thousand years. But it was not a continuous process: there were times when the fields were abandoned, and centuries later cultivated again.
