The Mosque of Amr ibn al-As, also known as the Mosque of Al-Fath, is one of the oldest mosques in Cairo, built during the reign of Amr ibn al-As in the city of Fustat. Its original area was 50 x 30 cubits, and it had six doors. After several expansions, its area increased to about 24,000 cubits, and it is currently 120 x 110 meters. In 564 AH, the mosque was burned during the Crusader campaign on Fustat. Saladin rebuilt it in 568 AH, including the large decorated mihrab.
