Shahreza (Persian: شهرضا)[a] is a city in the Central District of Shahreza County, Isfahan province, Iran, serving as capital of both the county and the district.[4] Shahreza was selected as the national city of pottery in Iran in 2015. The reason for this choice was the high skill of the artists and the unique soil of this city.[citation needed] It was one of the ancient territories of northern Pars (Persia) Satrapy in B.C. In the north of the county there is canyon of Orchiny (Orchine) that the main Iranian north-south high way passes through. The huge castle of Qomsheh was the latest place constructed by the Safavid Empire before the occupation of the capital Isfahan in the last of Safavid ages when Afghans captured it.
