Sumela Monastery

With its stunning, lonely setting, built into a cliff face, Sumela Monastery (Monastery of the Virgin Mary) is the star attraction for visitors along the Black Sea Coast. Wandering around this abandoned religious complex, with its church interiors crammed with dazzling and vibrant frescoes, is a must for anyone who makes the long journey to Turkey's northeast region. The monastery first opened during the Byzantine era and was only closed in 1923. Today, wandering its empty cells, it's easy to imagine the isolated lives of the monks who once lived here.
