Al-Nabi Mosque, also called Soltani Mosque, is one of Qazvin's major historic mosques. The present complex dates mainly from 1787, though parts of the site go back to the Safavid period.
Its scale, courtyard, and tiled prayer spaces make it a worthwhile stop in central Qazvin, close enough to combine with Sa'd al-Saltaneh Caravanserai, Jameh Mosque, and other old-city sights.
