Aksaray, where the valley is located, was a very important center in the birth of Christianity. The important founders of the Basilica of Basilica and Gregorius of Nazianos came to the region in the 4th century and established a Greek - Slavic monastery. In contrast to the monastic life in Egypt and Syria, they tried to spread their religion among people who spoke different languages without interrupting the world. The first center of this movement was the Belisırma Village from Ihlara Valley stops. To describe Christianity to the locals who do not know Latin, the interior of the churches is furnished with frescoes in which they draw the scenes of Jesus, scenes from the Bible and saints. Very few of the churches bearing the traces of this formation at the 14-kilometer valley floor were able to maintain their vitality until the present day. The painting technique used in frescos is classified as two categories. The churches in the Ihlara region were called Cappadocia type, while the churches around Belisırma were considered Byzantine type.
Cappadocia Type Churches in the town of Ihlara: In these early Christian churches, the biblical scenes in the frescoes were painted according to the understanding of the Basilica of Kayseri and Gregorius of Nazianos. In this category, except for the last Roman church of the Agora Church, there have been quite long descriptions of the eastern traces of the Egyptian and Syrian monastic life.
