Na’in lies 170 km north of Yazd and 140 km east of Isfahan 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 1960s 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.

Besides its magnificent monuments, Na’in is also famous for high-quality carpets and wool textile and home made pastry ( copachoo) .

It has one of the earliest remaining mosques in Iran, and has a Sassanid era fort, now in ruins, called Narin Ghaleh.

The initial construction of Jame Mosque dates back to the 8th Century CE, but the whole of the complex has been constructed incrementally.

One of the oldest mosques in Iran, its magnificent plasterwork over the niche, the marvellous brickwork around the yard, and its silent basement—which may have been used as a fire temple before the mosque was built here—are only a few of the remarkable features of this mosque.
