The history of Nain appears to go back to pre-Islamic times, but no information about it has survived. It is famous for its big castle and its congregational mosque, the Jameh Mosque of Nain. It was described by medieval historians to have been in the sardsīr ("cooler highland areas"), and being a subordinate to either Yazd or Isfahan, despite being part of the administration of the Fars Province. The historian and geographer Hamdallah Mustawfi reported that the walls of Nain's castle, which are still present as mud brick remnants, were four thousand paces long. The nearby mountains' silver mines are also described by the geographers. During the Safavid era, the kaolinite of Nain was utilized to manufacture porcelain at the city of Kashan.[4]

Under the Buyid dynasty (934–1062), the Jameh Mosque of Nain was constructed.[4]
