Here’s a brief background for readers who might not be familiar with Delos. The island, situated just over 2 km west of Mykonos, is one of the most important historic and archaeological sites in Greece. It’s often called “the sacred island” and “the island of light” because, in Greek mythology, it was the birthplace of Apollo, the god of light, and Artemis, the goddess of night light.

During its glory days between 166 BC and 69 BC, Delos was a wealthy shipping hub and one of the world’s leading centers of commerce. Home to more than 30,000 people, the city went into decline after it was looted and razed in two separate attacks; residents gradually left the island, and eventually Delos was abandoned completely and almost forgotten.

Delos regained international attention when archaeologists began excavating its ruins in 1872. Small numbers of travelers, mainly from Europe, started visiting the island to view the fascinating historic sites that were gradually being unearthed. Over the decades, the trickle of tourists turned into a steady stream of sightseers from around the world, and today Delos is a top tourist attraction drawing more than 100,000 visitors each year. Delos is widely considered a “must see” attraction for people visiting Mykonos, and I personally recommend that visitors schedule a half-day trip to Delos during their Mykonos holidays, especially if it’s their first visit to Greece.

In 1990, Delos was added to the UNESCO World Heritage List. A description for UNESCO’s Delos listing says “The archaeological site is exceptionally extensive and rich and conveys the image of a great cosmopolitan Mediterranean port.”

And according to the Delos page on Visit Greece, the official tourism web site for Greece, “nowhere else in the Globe is there a natural insular archaeological site of this size and importance. No other island on Earth hosts so many monumental antiquities from the Archaic, the Classical, and the Hellenistic periods, i.e. the centuries of the great Greek art, on a territory used exclusively as an archaeological site.”
