Sun-seekers flock south for Greece holidays, chasing a vision of cobalt seas, blue-and-white island dwellings, orange and lemon groves, and leisurely meals that continue deep into the night. Visitors raised on the history of ancient Athens and Sparta, stories of Thermopylae and Marathon, Greek philosophy and poetry and art, can see where it all happened. Crete, cradle of Europe’s first civilization; the Cycladic Santorini with its whitewashed houses and blue-domed churches; well-watered Corfu and its sister Ionian islands — all grip our imaginations.
