Delos is a mythical place where the twins Apollo and Artemis were born. One of the best greek islands is Delos which holds some absolute spiritual significance. There is some amazing legend associated with Delos related to Leto, the mother of the twins who was apparently seduced by Zeus. For such reasons, Delos is considered truly sacred even after its destruction in 88 BC. The island after that has gone through purification and today serves as an amazing historical site. This is what makes Delos one of the best places in Greece for historians and archaeologists.
