This essay explores the monumental intent of Cairo's Mamluk architecture by focusing on al-Darb al-Ahmar, a major thoroughfare along the route of royal processions that linked the citadel to the heart of the city. With a rather restrained number of architectural components, Mamluk patrons competed with each other in endowing monuments along the street that emphasized verticality, visibility, and domination of their urban surroundings. Al-Darb al-Ahmar was consequently transformed into a venue of exhibition where the Mamluks displayed their elaborate spatial, visual, and ceremonial grandeur and ultimately signs of their power. These Mamluk buildings attest to the outstanding monumental properties of Mamluk architecture and frame a street that, despite its deteriorating state, still exudes a bygone royal majesty.
