وادي النطرون
There were three monastic centres in the Nitrian Desert in Late Antiquity. Around 330, Macarius the Egyptian established a monastic colony in the Wadi El Natrun (Scetis), far from cultivable land. In the 330s, Saint Amun founded Nitria, only southeast of Alexandria, using the rules of Saint Anthony. He founded a second centre, Kellia, on Anthony's suggestion, deeper into the desert. Kellia has been the object of scientific excavations. Only Scetis in the Wadi El Natrun remains a monastic site today.
