Pope Shenouda I of Alexandria was the 55th Coptic Pope of Alexandria and Patriarch of the See of St. Mark (859-880). He is commemorated in the Coptic Synaxarion on the 1st day of Baramudah. As a result of the attacks by the Berbers and the Bedouins, Pope Shenouda I built walls around the monasteries of the Nitrian Desert. Their height varies between ten and eleven meters, and their widths are about two meters. They were also covered with a thick layer of plaster.
