Abstract
The Ayyubid era witnessed great interest in religious buildings represented in mosques, scenes, schools, gorges, and grottoes. The Mamluk state followed them, but the Mamluk urban character was distinguished by delicate decorations and marble of various colours. So, Mamluk Cairo was truly a great museum. Hence, the study sheds light on the most famous religious buildings in both countries, with diligence in providing an accurate description of their distinct urban nature in showing unity and diversity in this aspect.
