Deir Es-Suryani, as the name suggests, was a community of Syrian monks and its neighbor, Deir Anba Bishoi, is of typical design with a tiny round-domed fourth-century church and inner defensive bastion dating from the ninth century.
Deir Anba Bishoi had defensive capabilities in case of an attack.
The community of Syrian monks was known as Al-Swami Ala Bim.
