Isfahan old Jameh Mosque

Masjed-e Jāme’ is the oldest Friday (congregational) mosque in Iran, located in the historical centre of Isfahan. The monument illustrates a sequence of architectural construction and decorative styles of different periods in Iranian Islamic architecture, covering 12 centuries, most predominantly the Abbasid, Buyid, Seljuq, Ilkhanid, Muzzafarid, Timurid and Safavid eras. Following its Seljuq expansion and the characteristic introduction of the four iwans (Chahar Ayvān) around the courtyard as well as two extraordinary domes, the mosque became the prototype of a distinctive Islamic architectural style.

The prototype character is well illustrated in the earliest double-shell ribbed Nezam al-Molk dome, the first use of the four iwan (Chahar Ayvān) typology in Islamic architecture, as well as the textbook character of the Masjed-e Jāme’ as a compilation of Islamic architectural styles. The Masjed-e Jāme’ of Isfahan is an outstanding example of innovation in architectural adaptation and technology applied during the restoration and expansion of an earlier mosque complex during the Seljuq era, which has been further enlarged during later Islamic periods by addition of high quality extensions and decoration.
