Six kilometers from Karacaviran is the village of Lexiles. It is remarkable that here is the Church "Tagar kilisesi", built in honor of St. Theodora. Three kilometers away is the necropolis.

This Greek Church is very ancient building. It was built in the 11th century.The Church had a T-shaped structure, which is unique among the churches of Cappadocia. It was originally covered with a dome. Later, the dome collapsed and the roof was covered with glass. On the second floor of the gallery can be accessed by stairs.

Perfectly preserved and have survived murals, deposited on the inner wall. In laws are clear stylistic differences, this is because they were made by three different artists working here in different periods of time. They depict scenes from the Bible: the Annunciation, the birth of Christ, the appearance of prophets, apostles, Jesus on the cross, the angels Gabriel and Michael, images of saints in medallions.

The Church was opened on 15 may 1858 with the permission of the Ottoman Sultan Abdulmejid at the request of Christians Malatapay (so Derinkuyu was called in those days), as evidenced by a plaque located at the Western entrance. To date, some of the letters in this inscription collapsed, however, preserved the elevation of the cross. Left and right there are other reliefs, such as the figure of St. George. In addition, in fairly good condition and is the bell tower. After the famous "population exchange" the Church was used for various household needs. Today it is closed to visitors, and inside it is nothing. However once or twice a year open it periodically to conduct the service. This happens at Easter and Christmas.

According to some extant evidence, Saint Theodore served in the Byzantine army under the name of captain Teodorica. To perform military duty related to her family, she was forced to go to the service, dressed in men's clothing. In the service of Theodore was unjustly accused of illegal activities and murdered on the spot where now is the Church.Another legend says that St. Theodore was from the Macedonian Royal dynasty and was the daughter of the Emperor Constantine. She rules in 1055-1056, until the authorities came the ruler Mikhail Military. According to one killed her, but for other Theodore fell seriously ill and died.
