Isfahan is a province in Central Iran.
Esfahan (Es·fa·han (ĕs'fə-hän') or Is·fa·han (Persian: اصفهان) is a city in central Iran. Located south of Tehran, it is considered not only by the locals to be one of the most beautiful cities in the world. An ancient town and capital of Persia from 1598 to 1722, it was long noted for its fine carpets and silver filigree. Today textile and steel mills take over their place. Its architecture, tree-lined boulevards and relaxed pace make it one of the highlights of Iran's cities. The capital of Esfahan Province, and once the country's capital, the Persians call it "Nesf-e-Jahan", meaning "Half The World".
Na’in (also known as Naein and Naeen) lies 170 km north of Yazd and 140 km east of Esfahan and the current population is about 75,000. With an area of almost 35,000 km², Na’in lies at an altitude of 1545 m above sea level. Like much of the Iranian plateau, it has a desert climate, with a maximum temperature of 41°C in summer, and a minimum of -9°C in winter. More than 3,000 years ago the Persians learned how to construct aqueducts underground (qanat in Persianکاریز, or kariz) to bring water from the mountains to the plains. In the 1960's this ancient system provided more than 70 percent of the water used in Iran and Na’in is one of the best places in all the world to see these qanats functioning. Unique to Na’in are some of the most outstanding monuments in all of Iran: the Jame Mosque, one of the first four mosques built in Iran after the Arab invasion; the Pre-Islamic Narej Fortress; a Pirnia traditional house; the Old Bazaar; Rigareh, a qanat-based watermill; and a Zurkhaneh (a place for traditional sport). Besides its magnificent monuments, Na’in is also famous for high-quality carpets and wool textiles.
Kashan is a city in the Isfahan province of Iran. Kashan is the first of the large oases along the Qom-Kerman road which runs along the edge of the central deserts of Iran. Its charm is thus mainly due to the contrast between the parched immensities of the deserts and the greenery of the well-tended oasis. Archeological discoveries in the Sialk Hillocks which lie 2.5 miles (4 km) west of Kashan reveal that this region was one of the primary centers of civilization in pre-historic ages. Hence Kashan dates back to the Elamite period of Iran. The Sialk ziggurat still stands today in the suburbs of Kashan after 7000 years. After world known Iranian historical cities such as Isfahan and Shiraz, Kashan is a common destination for foreign tourists due to numerous historical places.
