"Delphi - Nauplia - Mycenae - Athens"

Also very archaeologically significant, Delphi combines historical site with modern Greek town.

If myths are to be believed, it was home to the most important of Greek oracles - the Delphic oracle and also a place to worship the god Apollo.

Delphi also played host to the the Pythian Games, where Greek athletes competed annually from 586BC - it did not rank as highly on the calendar of events as the Olympic Games later would, but they were significant nonetheless.

Delphi was described as being at the 'centre of the world', which made it much more important in the ancient Greeks' eyes and to which they paid homage in their own way...

The seaside and also port town of Nauplia/Nafplio was the first capital of modern Greece, now the capital of the peripheral unit of Argolis.  Finally, the archaeological site of Mycenae is found just south-west of Athens and was once one of the major centres of Greek civilization, with a military stronghold which dominated much of southern Greece.
