Nayreez is 1,140 km. from Tehran. It is situated in the southeast of the Bakhtegan Lake. This city has a moderate climate in north and is warm in the south. In clay inscriptions of Persepolis it is mentioned as “Narizi”. Ancient "Arsiman" in Natanz is 6000 years old.
Neyriz is mentioned in the Persepolis Administrative Archives of the Achaemenid Empire under the Elamite name Narezzash, which reflects its Old Persian name Narecha. The city was known for its armorers, which has been connected to the historical evidence of iron mining in the region. However, no direct archaeological evidence of the Achaemenid city has been found.
