Inca mythology refer to the island as the location where Viracocha commanded the rising of the moon. Archeological ruins of an Incan nunnery were found on the eastern shore. This nunnery was used by the Incan's to house the virgins that they would then sacrifice later. They had levels of classifications for the virgins, essentially spectacular, medium and regular. These sacrifices supposedly brought great honor to their families, when they were savagely beaten because they believed their screams would reach the heavens, the louder they were. A very humbling and quiet, little island gives you a lot to contemplate regarding the many thousands of lost lives and dead Indians from this area.
