Old Cairo (Egyptian Arabic: Masr el Qadīma) is a part of Cairo, Egypt, that contains the remnants of those cities which were capitals before Cairo, such as Fustat, as well as some other elements from the city's varied history. For example, it encompasses Coptic Cairo and its many old churches and ruins of Roman fortifications. Modern tourists visit locations such as the Coptic Museum, the Babylon Fortress, the Hanging Church and other Coptic churches, the Ben Ezra Synagogue and the Mosque of Amr ibn al-As.
