Jame Mosque of Hamadan is built similar to the style of Qajar mosques and maybe its construction has started at the time of Fath-Ali Shah or at the beginning of the reign of Mohammad Shah Qajar. In addition, it is reported that this mosque has had an older building and later some of its shabistans  are reconstructed. The current building of the mosque belongs to Qajar Period; however, the north shabistan and minarets of north porch as well as minarets of northeast entrance of the mosque are the works of contemporary period.
