The
cleansing of Persepolis sewage system in the depth
of 7 meters have led to the discovery of more
potsherds, brining the number of pieces found so
far to a total 600.
Persepolis complex, located near Shiraz, is one of
Iran’s registered world heritage sites. The
canals of the complex which run beneath the podium
and palaces form a systematically designed system.
So far more than 2 kilometers of the system has
been identified and is under study.
According to head of the excavation team of the
canals, Alireza Asgari, the dredging work in the
canals is now progressing very slowly due to lack
of air in the depth of 7 meters and the hardness
of the sediments inside the canals.
“So far, some 600 potsherds and eight sediment
layers have been identified. Most of these clay
pieces have been pulled out from the lower
layers,” explained Asgari.
The potsherds are of different types and are
colored in orange, red, and yellow.
Another discovery of experts during the recent
work has been a canal blocked by large rock, the
reason of which is not yet known.
