The construction project of the mosque was started in 1879 upon the order of Mirza Hosein Sepahsalar, a Grand Vizier of Iran during the reign of Naser al-Din Shah Qajar, and the first phase of construction was finished after five years since it was started.

[2] The main entrance portal and the facade are of a quite distinctive Qajar style.

Two massive minarets flank the recessed entrance, which leads into a courtyard surrounded by twin-storeyed arcades of college rooms; in all there are some 60 chambers.

[3] Tiles with full-blown floral motifs in a typically flamboyant Qajar style decorate the courtyard, while a tile inscription band gives details of the original endowment.
