Ibrahim Pasha
Official Egyptian records confirm that Ibrahim Pasha built multiple Cairo palaces, including Al-Qasr Al-Aly and El-Maghara. Their existence is verified, but their precise architectural histories remain under reconstruction.
Prince Omar Toussoun
The audit has now promoted the Shubra palace into the permanent RPR. A second Cairo residence, Palais Toussoun in Zamalek, is classified as a later-acquired dynastic household residence. Alexandria contained an even larger Toussoun property network, but those buildings remain in the research queue until each can be identified independently.
Method
A palace enters the permanent registry only when a source supports the building itself. A family biography that merely says a prince “had several palaces” creates research leads, not automatic RPR records.
