Cehennemağzı Caves
Hellağzı Caves are located in Zonguldak Ereğli District, İnönü Neighborhood. This region is known as the Acheron Valley of Antiquity. The Nefesağzı Caves, which operate as a ruin site affiliated to the Ereğli Museum, consist of three caves lined up side by side. The first cave is arranged in two parts. In the first part, the floor is paved with original plant and geometric motif mosaics. A small apse was opened on the east wall of the second section and there are stepped steps in front of it. This cave, which is a very old Christian church, was used as a secret place of worship in the first years of the spread of Christianity. The second cave is located on the slope at a height of 10-12 meters by the roadside and is called Koca Yusuf Cave by the local people. The cave, which is descended with the help of a 3-step vertical ladder by passing through a narrow entrance on the slope, continues into the mountain for 1.5 kilometers. Since a rock falling from the ceiling blocked the way in the 1960s, it is only possible to go as deep as 350 meters. The cave, which can be understood from the traces of masons, covers an area of approximately 400 square meters and is supported by two elephant feet. The third cave is the largest in terms of surface area. The ground is covered with ground water. The cave, which was made by human hands, served as a water cistern for the first and second caves.
