Psychro Cave is an ancient Minoan sacred cave in the Lasithi district of eastern Crete. Psychro is associated with the Diktaean Cave, the putative site of Zeus' birth. According to Hesiod, Theogony 477, Rhea gave birth to Zeus in a cave of Mount Aegaeon, near Lyttos; since the late nineteenth century the cave above the modern village of Psychro has been identified with this sanctuary. Psychro is 1,025 meters above sea level. The cave is located in the prefecture of Lasithi.
The Dictaean cave is famous in Greek mythology as the place where Amalthea, perhaps known in Crete as Dikte, nurtured the infant Zeus with her goat's milk, the mythic connection to the long use as a site of cult attested here by its archaeology. The nurse of Zeus, who was charged by Rhea to raise the infant Zeus in secret here, to protect him from his father Cronus (Krónos) is also called the nymph Adrasteia in some contexts.
