Gorgeous churches and monasteries exist all over the world in abundance, but this is the first and largest place of worship we have run across in a cave. The Cave Church of St. Simon in Mokattam, Egypt, is a beautiful work of natural architecture and offers up a place for the Zabbaleen people to practice their religion.
The church was established in 1975, and the space ultimately stood the test of time and is able to hold 20,000 people in its amphitheater. Though these people aren’t your traditional Muslim religion of the general country, it’s obvious that they still take their beliefs seriously– and are able to freely in the Mokattam area. Even with its vast capacity, St. Simon’s ‘Tanner’ is only one of seven cave churches nestled within the caves of Mokattam Mountain.
