Greece

Sounion - White Doric columns on the last cliff of Attica, built for Poseidon, god of the sea, and still the mark every sailor looks for when the land of Athens falls astern.

Epidauros -This is the finest surviving Greek theatre, still used in summer, set inside the healing sanctuary of Asklepios a short taxi inland from the Argolic Gulf.

Delphi - This is Apollo’s oracle on the mountain, the place Greek cities treated as the navel of their world, and the place where a general might still ask whether he ought to put to sea.

Mycenae - This is the citadel Homer called “Mycenae, rich in gold,” the hill from which Agamemnon is said to have led the ships to Troy, and the place where the Bronze Age still has a gate you can walk through.

Monemvasia - From a few miles offshore the rock looks like an island citadel that has come unmoored from the mainland, until the causeway shows itself and you see why the town has only one gate.
