Once a week hundreds gather at the Cave Church in Moqattam, after the prayer, a coptic priest performs exorcism or healing blessing to some of the believers. With a cross and holy water he fights spiritual entities and demons.  The Monastery of St. Simon the Tanner is the largest and it has an amphitheater with a seating capacity of 20,000 making it the largest church in the Middle East. It is named after the Coptic Saint, Simon the Tanner, who lived at the end of the 10th century, when Egypt was ruled by the Muslim Fatimid Caliph Al-Muizz Lideenillah. Simon the Tanner is the Coptic Saint who is associated with the legend of the moving of the Mokattam Mountain.
