Strasbourg is immersed in Franco-German culture and although violently disputed throughout history, has been a cultural bridge between France and Germany for centuries, especially through the University of Strasbourg, currently the second-largest in France, and the coexistence of Catholic and Protestant culture. It is also home to the largest Islamic place of worship in France, the Strasbourg Grand Mosque.

Alexandria was too much like a European city to be novel, and we soon tired of it. So, they take a train to Cairo October 4.

Old Cairo contains the remnants of those cities which were capitals before al-Qahira, such as Fustat, al-Askar and al-Qatta'i. These are the location of the Mosque of Amr and the Mosque of ibn Tulun, though little else remains today. This area also 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.
