The Persian-Islamic style mosque has been under construction since the 1990s. Upon completion, the mosque will have the world's biggest iwan.[3][4][5] When completed, the mosque will surpass the Masjid al-Haram in Mecca, as of April 2025[update], the world's largest mosque.
History
The Grand Mosalla Mosque originated in a 1982 proposal to replace the University of Tehran as the primary location for weekly Friday prayer.[6] A large section of land in Abbas Abad, the original site for the never-materialized pre-Revolution megaproject Shahestan Pahlavi, was allocated for the Grand Mosalla.[7]
On 19 February 1985, a public announcement was issued, calling on talented and experienced designers to submit drafts for the mosque's design. The competition was held in 1986 with Mohammad Karim Pirnia, Mehdi Chamran, Bagher Ayatollahzadeh Shirazi, Ali Ghaffari, and Mehdi Hodjat as the jury members, and with the participation of 36 native and foreign individuals from Japan, Syria, Pakistan, and the Netherlands, as well as legal entities. On 1990, Dr. Parviz Moayed Ahd's design was confirmed for the Mosalla.[8]
As of April 2025[update], more than 30 years after the design was finalized, the Grand Mosalla remained under construction, though finished sections of the building were in use.[6] In 2017, the Financial Tribune called the condition of the project "dismal" and "unacceptable", and Governor General of Tehran Province Hussein Hashemi urged Tehran City Council to prioritize the mosque's completion.[6]
Use
The Grand Mosalla Mosque is used for Friday prayer (jāmeh) and during Eid al-Fitr. Ayatollah Seyyed Ali Khamenei has led prayers at the mosque in 2024 and 2025[9][10] and the mosque was a focal point for worship following the sudden death of Iranian President, Ebrahim Raisi.[11]
The mosque complex is also used as a community center and a venue for local and national events, including the Tehran International Book Fair,[12][13] International Holy Quran Exhibition,[14] International Exhibition of Investment Opportunities in Iran's Mines and Mining Industries,[15] International Handicrafts Exhibition,[16] and the Tehran Game Exhibition, among other events.
Access
The Grand Mosalla Mosque is served by the Mosalla Imam Khomeini Metro Station, a Tehran Metro station located in the Grand Mosalla, next to the Qasem Soleimani Expressway.[17] It also has a bus rapid transit station in Line 5: Science & Tech Terminal to Argentina Square Beihaghi Terminal.[18][19]
