It is located at Messaria 2.5 km. southeast of Megalo Chorio. It has a 21 m. diameter, a maximum height of 4.5 m., and covers an area of 200 m² , separated into two unequal chambers by a stalagmite. Paleontological excavations carried out in the 1970s revealed numerous bones of dwarf elephants and other animals (deer, turtles, rodents) and stone tools of the Neolithic period (8000 BC). Chardakio Cave hides other secrets: Volcanic material and at least two zones with phosphorus compounds that lead to fossilized bones have been found in deeper layers.
