After the "Gates of Ibn-Tulun", here's the "Light of Ibn-Tulun" (from the same mosque in Cairo of course). With the risk of repeating on the same theme here, but I just absolutely adored this empty and moody historical place in the middle of the most chaotic city of Egypt.

For the EXIF lovers: it's 2500 ISO :-) I just love the 5DmkII ...
