The Mosque of Amr ibn al-As also called the Mosque of Amr, was originally built in 641–642 AD, as the center of the newly founded capital of Egypt, Fustat. The original structure was the first mosque ever built in Egypt and the whole of Africa. Through the twentieth century, it was the fourth largest mosque in the Islamic world.
The location for the mosque was the site of the tent of the commander of the Muslim army, general Amr ibn al-As. One corner of the mosque contains the tomb of his son, ‘Abd Allah ibn ‘Amr ibn al-‘As. Due to extensive reconstruction over the centuries nothing of the original building remains, but the rebuilt Mosque is a prominent landmark and can be seen in what today is known as Old Cairo. It is an active mosque with a devout congregation, and when prayers are not taking place, it is also open to visitors and tourists.
