The western porch, however, has no entrance and consists of two rows of columns. This portico was completely destroyed and has been rebuilt during the contemporary restorations of the building. History and restorations 
In the sixth century A.H., the family of Abu Sa'd Varamini, a wealthy Shia family from that era, built a mosque in Varamin, but the current building was built in 722 A.H. (1322 CE) by the order of Izz al-Din al-Quhadhi. Apparently, the mosque was damaged due to a disaster, and in the ninth century A.H. (15th century CE), Amir Yusef Khajeh ordered the building to be restored. After that, it was not maintained for 500 years. For instance, Jane Dieulafoy, who visited the mosque during the Qajar period, wrote that no one prays there as peasants are afraid if the dome collapses and 'infidel foreigners' can watch it without any restrictions. This mosque was registered in Iran's national list of heritage buildings in 1932 CE and its current boundaries were defined. It was excavated by archaeologists in 1960s and 1970s and was restored in the 80s. See also
