Cennet and Cehennem caves
MERSİN
It is possible to reach the bottom of Cennet by a primitive staircase composed of 300 steps. At the bottom towards south, there is a smaller and 150 steps deeper cave. In this cave are the ruins of a monastery dedicated to Virgin Mary
Cennet and Cehennem are situated next to each other. Cehennem is a deeper sinkhole. Moreover, the upper edge of its opening is concave. So, it is impossible to reach the bottom of Cehennem.
