Turkey is a home of civilizations, of culture, and of so much more that it's no surprise that it's also a home to religions. Architecturally and spiritually, these monasteries are spellbinding remains of an era gone by, and of some of the first Christian communities anywhere in the world. The first on this list is no surprise, as Sumela is a monastery set in one of the more stunning locations you'll ever see in any of Turkey's monasteries. A massive complex cut into the face of the rock, architecturally it's like nothing you've ever seen before. It underwent restoration recently for a number of years and has only just reopened, meaning that this 4th century monastery is as incredible to visit now as it's ever been. Mor Gabriel Monastery, or the monastery of St. Gabriel, is the oldest surviving Syriac Orthodox monastery in the world. It was founded in 397 in the beautiful, historic province of Mardin, and by the 6th century was one of the most important monasteries in all of Christianity.
