Delos was considered so sacred that in antiquity, births and deaths were forbidden on the island to maintain purity.
The island functioned as a major slave trading center, with up to 10,000 slaves reportedly sold in a single day during the Roman era.
The famous Terrace of the Lions originally featured at least nine marble lions, though only five remain in situ today.
The House of Dionysus features an exceptionally well-preserved mosaic floor depicting the god riding a leopard.
Delos served as the treasury for the Delian League, the alliance of Greek city-states led by Athens during the 5th century BC.
Archaeological excavations on the island have been conducted primarily by the French School at Athens since 1872.
The island has no permanent residents other than the archaeological staff and guards.
The water table in the Sacred Lake area has been drained since the 1920s to prevent the spread of malaria.
The theatre is noted for its advanced ancient acoustics and sophisticated drainage system.
The Archaeological Site of Delos is a UNESCO World Heritage site and the legendary birthplace of the deities Apollo and Artemis in Greek mythology. Located on a near-entirely uninhabited island in the Cyclades, the site contains extensive ruins dating from the 3rd millennium BC to the 1st century AD. It served as a major pan-Hellenic religious sanctuary and, following its declaration as a free port in 166 BC, a massive Mediterranean commercial hub. Visitors can explore the Terrace of the Lions, a row of archaic marble statues dedicated to Apollo, and the remains of private residences with intricate floor mosaics. The site includes the Sacred Lake, a circular depression marking the traditional spot of Apollo's birth. Structures span various eras, including Hellenistic residential quarters, the Temple of the Delians, and the Theatre of Delos. The entire island is an open-air museum, requiring significant walking across uneven, exposed terrain. Strict conservation laws prohibit the removal of even the smallest stone fragments from the island.

Wear sturdy, closed-toe walking shoes to navigate the loose gravel and uneven stone pathways.
Allow ample time to visit the onsite museum before trekking through the outer ruins.
Do not plan a visit on a windy day, as boat crossings can be frequently canceled due to high seas.
