A wall along 115 km that dates back to 2400 years ago.
In western Iran a wall along 115 has been discovered, km near the city Sar Pol- and Zahab in the province of Kermanshah, they call it the Persian Wall
The Iranian archaeologists who are studying it immediately after the discovery define it as the Persian Wall and declare that this stone wall was built between the 4th century BC and the 6th century AD C. and it is a new discovery that still needs to be studied.
Preliminary investigations confirm that the wall made of about one million cubic meters of stone, a work that most likely required a huge workforce in addition to a long time and a very large amount of materials.
The population that lives in the neighboring area of this wall, had known for some time of the presence of this wall but they did not know the history and call it Gawri wall
Along the wall are visible remains of some structures which, according to the researchers, may have been turrets, if not actual buildings, probably occupied by guards. In addition to stone, researchers have noticed the use of pebbles and boulders taken from local areas as well as plaster mortar.
The remains are scarce enough so that one is not even sure of its real height even if an estimate has been made: about three meters high by four meters wide.
