I am sure "normal" tours would never leed you to the Mokkatam mountain with its both absolute special sigths of Cairo. Coming from the Citadelle you have to find the road towards the mountain into the Zabbaleen village. Here the "garbage people" of Cairo live. Most of them are Christians. They collect and sort the garbage of the inhabitants. Its their income and basis of life which now slowly is taken over by "normal" industrial garbage companies which not at all give the same service like the Zabbaleen did. Its a hard challenge for your nose and eyes to see all the garbage and the children in between. Visiting it a second time after about 5 years we are positive surprised about changes in cleanses. Much more nice shops along the road invite for a stop.
The Sisters of Mercy (Mother Theresa) and Sr. Emmanuelle (Sister of Notre Dame de Sion) have been very much engaged in support those peoples education and health care.
You just drive up to a right turn with a sign for the St. Simon Monastery. Then you already enter it through large door. You will find huge churches cut into the rock and amazing reliefs and figures along the wall done by an polish artist.
Sometimes huge groups of pilgrims like to visit this special place.
Here you get an impression of the life of a part of the inhabitants of Cairo which is very different to all other places.
