This enduring bastion of Coptic Christianity dates back to the mid 4th century AD making it one of the oldest in-use houses of worship in the world (not THE oldest, but one of them). It started as a community of like minded Christians organized by a priest named Marcarius (now St. Marcarius the Great).
The monastery has been destroyed and rebuilt many times throughout history, and currently contains 5 churches, including one containing the relics of St. Moses the Black, the thief/murderer turned monk described in the very late hint.
