Mosque of Amr Ibn al-As is also known as the Mosque of Amr in Cairo, it is the first ever mosque built in Egypt and the African Continent. It is believed that the Muslim commander Amr pitched his tent here so it was the start of Fustat (Old Cairo).
The very first mosque on current site was built in between 641- 642. Though originally a modest structure, it was destroyed and restored so often that it is impossible to know the appearance of the first building. The Umayyad ʿAbd al-ʿAziz ibn Marwan demolished the mosque and rebuilt it, probably following closely the original dimensions, in 698. In 827 the Abbasids rebuilt it, doubling its size.
