The local Coptic church in Mokattam Village was established in 1975. After the establishment of the church, the Zabbaleen felt more secure in their location and only then began to use more permanent building materials, such as stone and bricks, for their homes. Given their previous experience of eviction from Giza in 1970, the Zabbaleen had lived in temporary tin huts up till that point. In 1976, a large fire broke out in Manshiyat Nasir, which led to the beginning of the construction of the first church below the Mokattam mountain on a site of 1,000 square meters. More churches have been built into the caves found in Mokattam. Currently, there are seven cave churches hidden among the caves of Mokattam Mountain. The Monastery of St. Simon the Tanner is the largest and it has an amphitheater with a seating capacity of 20,000. This church is 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...

It is also known as 'the Synagogue of the Palestinians' or 'of the Jerusalemites'. Given the small population of Egyptian Jews, the synagogue is no longer active and is largely a tourism site and Jewish museum. The geniza or store room of the synagogue was found in the 19th century to contain a treasure of forgotten, stored-away Hebrew, Aramaic and Judeo-Arabic secular and sacred manuscripts. The collection of approximately 40,000 items, known as the Cairo Geniza, was brought to the University of Cambridge in Cambridge, England at the instigation of Solomon Schechter. It is now divided between several academic libraries, with the majority being kept at the Cambridge University Library.
