On the map you can see four churches, the first to the left of the Hellenistik Kule. Counting clockwise this is the last, on the map on the top side of the “Kanlıdivane obruğu”, I call it number 4.

It is the largest one as for what still remains, very impressive. The German Wikipedia has good information: "According to a donor inscription, the three-aisled basilica in the northeast of the sinkhole is called 4 Papylos Church. It was built at the end of the fifth century and is the youngest and best preserved basilica in Kanytelleis. Most of the walls are still up to 8 meters high. Only the south wall has completely broken away. To the west of the basilica is a forecourt 15 meters wide and around 10 meters deep. Half an arch still stands from a three-part, open arch position, the western entrance into the 3.60 meter deep and 14 meter wide narthex. The approximately 22-meter-long church space is divided by two arcades into two narrow aisles and a 6.20-meter-wide central nave, each with a door to the narthex. In the north wall, protruding stone supports indicate the position of the side gallery. The passage from the nave to the choir was vaulted by a high triumphal arch, of which the left approach can still be seen. The apse with twin windows stands in front of a straight choir closure."
