Just a couple of hundred yards due south of Qurqumas you will find the Mausoleum complex associated with Sultan Faraj ibn Barquq. This link will take you to a "live" Google map that shows the area. I highlighted the two buildings with red arrows. You may notice that a street junction in the form of an "X" marks the spot near the flyover bridge on Salah Salem.
This is a large active mosque. The street along the minaret side is tree-lined. The interior courtyard also displays a number of trees, which is quite a contrast to any other mosque that we have seen.
The carpets at the front are worth pausing for a close look.
This is probably one of the most photogenic mosques you will find other than Ibn Tulun.
