The Coptic White Monastery (Arabic: الدير أبيض), also The Monastery of Abba Shenouda (Coptic: ⲡⲙⲟⲛⲁⲥⲧⲏⲣⲓⲟⲛ ⲛ̀ⲧⲉ ⲁⲡⲁ ϣⲉⲛⲟⲩϯ) and The Athribian Monastery (Coptic: ⲡⲧⲱⲟⲩ ⲛ̀ⲁⲑⲣⲏⲃⲓ, romanized: eptōw enatʰrebi, lit. 'the mountain of Athribis') is a Coptic Orthodox monastery named after Saint Shenoute. It is located near the Upper Egyptian cities of Tahta and Sohag, and about two and a half miles (4.0 km) south-east of the Red Monastery. The name of the monastery is derived from the colour of the white limestone of its outside walls. The White Monastery is architecturally similar to the Red Monastery. The monastery had one of the largest Coptic libraries ever known with over 1,000 codices of which 10% survive.
