Natanz (Persian: نطنز) is the centre of a township of the same name in the Isfahan province of Iran. It is located 70km south-east of Kashan. The population of the township as of 1999 was 39,964.
Its bracing climate and locally-produced fruit (especially Natanz pears) are well-known in Iran. The famous Karkas mountain chain (Kuh-e Karkas) (meaning mountain of vultures), at an elevation of 3,899 meters, rises above the town, and locals point in its direction telling how the Achaemenian King, Darius III, was killed nearby.
