"The Iron Gate", was planned by (again) al-Zahir Ghazi, but built by his son Mohammad, and named at that time Bab al-Qanat, or Aqueduct Gate. This gate was built over again by the last Mamluk sultan, in 1509. According to this cryptic source, "It holds an unknown shrine within its walls". http://www.archnet.org/library/sites/one-site.tcl?site_id=5287
