The church consists of two parts; first a long nave then another section with a flat ceiling. Opposite to the entrance Christ is seen standing, with a young boy beside him. The first two figures on the upper right wall are St. Basil and St. Thomas. Then comes St. Onuphirious with a leaf covering her genital organ. According to the tale St. Onuphirious was a frivolous woman once. One day she prays God to protect her from Men. God accepts her will and uglifies her with beard and moustache and she retires into a secluded life.
The first figure on the upper left wall is St. Onosimos. Further on St. Theodor and St. George are represented as slaying the snake. Following on the left side, figures of Emperor Constantine and Empress Helena are seen with a cross between them. This Orthodox cross represents the good relationships between them and Cappadocians. The paintings of the Yilanli Church belong to the llth century. The church gets its name from the painting of a snake.
