The Cave of Zeus is a system of caves located on the slopes of Mount Ida, on the island of Crete, Greece. The deep cave has a single entrance and features beautiful stalagmites and stalactites. In antiquity it was a place of worship, because it was believed to be the cave where the goddess Rheahid the infantZeus, in order to protect him from his father Cronus. According to a variant of this legend, the Kouretes, a band of mythical warriors, undertook to dance their wild, noisy war dances in front of the cave, so that the clamour would keep Cronus from hearing the infant's crying. Excavations have revealed a large number of votive cult offerings on the site.
The Cave of Zeus may also refer to a cave by the same name on the Aegean island of Naxos.
