Goreme Open Air Museum 12;
In the 3rd century, priests with good character changed the region into a lively centre of Christian activity. In the 4th century Cappadocia became known as the land of the three saints; The Great St. Basil, Bishop of Kayseri; his brother St. Gregory of Nyssa, and St. Gregory of Nazianus. St. Basil founded small, secluded settlements far away from villages and towns. Daily worship was carried out under the supervision of a preacher. These groups were not, however, privileged groups separated from the community like similar communities in Egypt and Syria. St. Basil is important in that he introduced worship within the community in the churches of Cappadocia. Göreme Open Air Museum is the place where this kind of religious education was started. The same model was then introduced in Soğanlı, Ihlara and Açıksaray.
