Goharshad Mosque (Persian: مسجد گوهرشاد) is a grand congregational mosque built during the Timurid era in Mashhad, Razavi Khorasan Province, Iran, which now serves as one of the prayer halls within the Imam Reza shrine complex.

It was built by the order of Empress Goharshad, the wife of Shah Rukh of the Timurid dynasty in 1418 CE.

By the order of Mohammad Reza Shah, the tiles from the ancient dome were removed in the 1960s and the external shell was dismantled.

The thick, tower-like minarets, merging with the outer corners of the portal screen, extend to the ground and, together with the high foundation revetment of marble, give the ensemble the impression of solidity necessary to support its exuberant color.

The entire court facade is faced with enamel brick and mosaic faience of the finest quality.... Media related to Goharshad Mosque at Wikimedia Commons
