Eighteenth-century Twelver Shia mosque, the principal surviving sacral monument of pre-1827 (Persian-period) Yerevan. Commissioned by the Erivan khan Hoseyn Ali Khan. During the Soviet period the building was preserved, in part through the intervention of the poet Yeghishe Charents and other Armenian intellectuals, and used as the Yerevan museum of history. Renovated 1996–1999 with funding from the Islamic Republic of Iran and currently functions as a mosque under Iranian custodianship. Officially attributed by Armenia and Iran to Persian heritage; Azerbaijani state historiography categorises it as Azerbaijani heritage. The framing is itself contested.
