At the foot of Mount Didymos in Argolis there is a unique geological phenomenon. The earth has sunk in two places that resemble volcanic craters. Except that the huge holes in the earth were not created by a volcano or by meteorites hitting the ground, but by the subsidence of the ground due to the underground water of the mountain. The two craters, known as dolines or caves, are circular in shape and are visible from a great distance because of their size. One is located at the foot of the mountain and is called the large cave and the second, on the plain, is called the small cave. Prehistoric people used to flee there to protect themselves from natural phenomena and during the Turkish occupation, the inhabitants of the area used to carry nitro from the urine of animals from the big cave and make gunpowder for weapons. The smaller crater is overgrown with pine trees and two churches, St. George and Metamorphosis, are carved into its rocky walls. A downhill gallery resembling a well is the most ancient entrance to the cave. According to the local legend, this is where the cave of Cyclops was, from which Odysseus and his companions escaped. A second entrance, built by the monks, leads to the interior of the cave, where there are two carved churches, a stone pool, a small cistern and a hole known as the “Askitario” through which the hermits ascend with a rope and it is said that the horse of St. George left its mark there.
