The House and Waqf of Ibrahim Agha Mustahfizan lies in El Darb El Ahmar District between the Mosque of Khayrbak and the Mosque of Aqsunqur. Opposite to this building appears the remains of Rabe of Ibrahim Agha Mustahfizan. The House and Rabe were established in the Mamluk period by a commander of the janissary Citadel guards. The construction of this collection of monuments extended about 25 years. Most of these monuments are in ruins now except from the Perimeters.
