After the paved open space called the Agorá Kombetialistón (remains of a monumental altar) are the ruins of the Sacred Way, the Propylaia (monumental entrance), theHouse and the Stoa of the Naxiots, the temple of Artemis behind which lie pieces of the colossal Statue of Apollo, the Stoa of Antigonos Gonatás, and especially the traces of the temples of Apollo: the temple of Delian Apollo (completed in the 3C BC), and the Athenian temple (c 420 BC).

The Terrace of the Foreign Gods was built in the 2C BC to hold the shrines of the non-Greek divinities frequented by the many immigrants who lived on Delos. There are traces of the Shrine of the Syrian gods, of the Shrine of the Egyptian gods, and of the Iréon, a small temple dedicated to Hera. Not to be missed: the ascent of Mount Kynthos whose summit has traces of a shrine to Zeus and Athena (3C BC) and offers a magnificent panorama over Delos and the Cyclades.

This urban quarter was built in the Hellenistic period. Facing the Sacred Lake is the impressive Terrace of the Lions, the row of famous Archaic lions sculpted in Naxian marble (only five remain, now replaced by copies). The area includes the House of Hermes (2C BC); the Institution of the Poseidoniasts; the quite well-preserved Hellenistic Lake House; and the Museum which contains a remarkable series of Archaic sculptures.

The lively waterfront with its curved marble quays is lined by the arcades of the 18C town hall, a lonely little chapel dedicated to St Nicholas, patron saint of navigators, café terraces and craft shops all the way to Platía Mandos Mavrogenous, which bears the name of a local heroine who fought for her country's freedom. In 1823 she composed a famous letter extolling the struggle for Greek independence.
