Acropolis of Rhodes, Rhodes Town, Rhodes
Concierge.com's insider take:
The Hellenistic acropolis, built during the fourth century B.C., overlooks both the New and Old Towns from its perch atop Mount Smith. The site contains the ruins of several ancient buildings. The small reconstructed theater was probably used for events associated with the cult of Apollo; the stadium below still hosts occasional performances of classical tragedies. The three restored columns of the Temple of Apollo, a landmark for ships at sea, sit on a platform above the retaining wall behind the theater. To the north, the foundations of a temple to Zeus and to Athena Polias have been revealed. Visit in the late afternoon to see the ruins bathed by the setting sun.
