Wadi El Natrun
It is one of the three early Christian monastic centers located in the Nitrian Desert of the northwestern Nile Delta. The other two monastic centers are Nitria and Kellia. Scetis, now called Wadi El Natrun, is best known today because its ancient monasteries remain in use, unlike Nitria and Kellia which have only archaeological remains. The desertified valley around Scetis in particular may be called the Desert of Scetis.
