The Qadisha Valley is located in Northern Lebanon. The valley is a deep gorge created by the river, Kadisha, that is also known with the name of Nahr Abu Ali when it reaches Tripoli, Lebanon. The most scenic section of the valley is stretched for approximately twenty kilometers between Bsharri and Tourza.
The valley hosts some of the most ancient Christian monastic communities of the Middle East, including Deir Qannubin which used to be the See of the Maronite Patriarch, Deir Mar Elisha and Deir Mar Antonios Qozhaya which can be accessed from the town of Arbet Qozhaya.
In 1998, the UNESCO added the valley to the list of World Heritage Sites because it is one of the most important early Christian monastic settlements in the world.Historians believe that the Kadisha Valley has had monastic communities continuously since the earliest years of Christianity. UNESCO considers the monasteries of the Kadisha Valley as the most significant surviving examples of early Christian faith.
