The Qannubin Monastery (Deir Qannubin (دير قنوبين)), is on the northeast side of the Qadisha Valley. It is the oldest of the Maronite monasteries; although its foundation is often attributed to the Emperor Theodosius the Great in 375AD, it is more likely that it was established by a disciple of St Theodosius the Cenobite. For the most part it is cut into the rock cliff side - monastic cells, church, cloister, and accommodation for travelers.
