Kumistavi Cave

Also known as the Prometheus Cave. After Prometheus helped humans, he was chained in the Caucasus Mountains, ostensibly in this cave. Georgia has a similar myth to Prometheus save their hero is named Amirani. He introduces humans to metalworking and, like Prometheus, was chained in the Caucasus as punishment. 

The reason they call it Prometheus Cave instead of Amirani Cave is easy- marketing.
