This mosque was constructed by Goharshad (the wife of Shahrokh Teimoori), in 821 AH. This mosque has a large courtyard in the center with four portico. Beautiful inscriptions in Thuluth script (the work of Shahrokh’s son) adorn the walls. The most important section of this mosque is its southern portico which boasts of arches and valuable inscriptions. Along side this portico stand solid minarets with thickness of 6 m., with the same height of the portico itself, which help in supporting the ceiling and prevent the roof from collapsing.
In bombardments of the Russian forces in 1330 AH, the main dome of this mosque which was 15 m in dia. sustained a loss. This dome was demolished in the year 1339 AH. The current dome has been constructed (in keeping with the former circumference) with concrete. This mosque has gone under repair once during the Safavid reign and the other in the Qajar era.
