The Jameh Mosque of Nain, known also as the Alavian Mosque, is one of the early mosques in Iran, located in Nain City, Isfahan Province, which belongs to early Islam in the 9th century but it is still in use. Following the common architectural plan of the time, the Jameh Mosque of Nain was built based on a central rectangular courtyard surrounded by porches, introducing it as a Shabestany Mosque.
Originally, the mosque was built with semicircular arches that they were turned into pointed arches and their height increased as well in later eras. More than other elements, the mosque is known for its Menbar (alter) and a wooden door. Menbar is a stair stand that a clergy sits on its top to deliver his speech. Both the door and the Menbar are designed with floral and arabesque patterns.
There is also an inscription in Menbar in Arabic Naskh calligraphy that dates back to the 14th century. The calligraphy is adorned with patterns of trees and leaves while it also mentions the name of the person (Jamal Al-Din Malek Tojar) who has provided a budget for the construction of Menbar.
