Qift
Qift ( ; Keft or Kebto; Egyptian Gebtu; Coptos / Koptos; Roman Justinianopolis) is a city in the Qena Governorate of Egypt about north of Luxor, situated a little south of latitude 26° north, on the east bank of the Nile. In ancient times its proximity to the Red Sea made it an important trading emporium between India, Punt, Arabia Felix and the North. It was important for nearby gold and quartzite mines in the Eastern Desert, and as a starting point for expeditions to Punt (in modern Somalia) by way of the path through the Wadi Hammamat to the Red Sea port at Tjau (modern El Qoseir).

Pessinus remains a Catholic (formerly double) titular see.
