The Cave of Agio Galas is located on the beautiful island of Chios and was mapped in 1969. It is located at the northwestern tip of the island in the homonymous village that is sixty-five (65) kilometers from the city. The route itself to the village is magnificent. In fact, the village is built on the rock where the cave system is opened. It is a cave with special morphology and great archaeological importance.
The visitor passes through chambers and apartments full of impressive stalactite complexes which are revealed in spacious halls and labyrinthine chambers with balconies, windows, bridges, and burrows. There is also a legend about the cave.

It tells the story of a leper exiled by her father, the daughter of a Byzantine emperor, who was cured by drinking the milky liquid (“Holy Milk”) that dripped inside the cave. When after three years the King repented and sent her back, his envoys found her healed.

Did you know?
Caves in Greek mythology were identified with Tartarus who was a minor deity of the underworld, son of Pluto or Aether or Chaos and Gaia. Tartarus, however, seems to be at the same time a mythical place, called the same name, Tartarus. In Tartarus, according to ancient beliefs, the bad guys were tortured after their death. Homer mentions many persons who were sent to this place for their “living” crimes such as Tityon, Tantalus, and Sisyphus. The ancients believed that the entrances to Tartarus were the caves.
The belief that caves were entrances to Tartarus was so strong that it was even mentioned in ancient literature. For example, in the Odyssey, Homer describes how Odysseus and his men enter the cave of Polyphemus and are trapped there by the Cyclops.
