Yes, the more one knows about the destruction of the Citadel to build the Muhamamd Ali Mosque, the more it becomes hard to like that building. And with such a rich heritage of Egyptian Islamic architecture, that mosque completely turns its back on Egypt and tries to imitate the Ottomans.. poorly! I will see if I can find something on the gate, I am curious too. My sense is that many things connected to the Citadel are tough to date because it was such an ongoing work. But there ought to be something about this gate in Nasser Rabat’s book on the Citadel..

Aside:I used to love looking at the Citadel hill, but ever since learning that the Muhammad Ali Mosque was a recent structure built upon purposely destroyed Mamluke buildings, I now get annoyed whenever I see even photos of the place.
