Sumela Monastery's Secret

The Sumela Monastery, which was built in the 300s, is an incredible feat of architecture as it was constructed nearly 4,000 feet up the side of a cliff. Over the centuries, it was destroyed and rebuilt several times, particularly during the Byzantine Era. Unfortunately, it was left empty and abandoned in the 1920s. However, in recent times, it has been taken over by the Turkish government and restored for tourism purposes.
