The mysterious cave emits sounds that have no explanation

The cave of Davelis is located on Mount Pendelli, whose material was used for the construction of the Parthenon.

The cave has been named after a 19th century burglar. He and his gang used it as a secret place, and according to legend, there was a maze of tunnels leading to the Duchess's house, which was his girlfriend.

At the entrance of the cave, it's a 12th century Byzantine hermetic church on rock. A little deeper into the cave, prayers were made for Mr. Pan and remains confirming this can be seen at the Archaeological Museum in Athens.

The paths of former travelers, including some 19th-century English writers and early 20th-century writers, can be seen on one of the walls, the Kosovo Press broadcasts.

There is evidence that the Greek Army conducted confidential operations there, which made the cave closed to the public. It has also been associated with nuclear weapons, Cold War experiments and numerous conspiracy theories. The cult status was given to this pyramid - shaped cave because of the variety of stories of people who came to the mountain to visit it.

Evidently, they saw water coming out of the floor above, cat - shaped creatures walking up high, while with the strange electronic devices something was going on they were going off and not working. This cave can serve as a model set for a horror film, as the traces of cult rituals can be found there.

Dimitrios Makridopoulos, who has always been fascinated by the paranormal, has put in a camera and equipment that recorded unusual activities through radio frequencies.

The devices recorded strange sounds, shadows and characters, and, as he says, Dimitrios felt strange energy at the entrance as if it came from another world, writes “Ful Couch”. Experts explain that magnetism may be the reason, but the very cause they cannot explain.
