Only on Santorini, the volcanic Greek island where the legend of the sunken city of Atlantis likely originated, will you find luxury hotels that are -- well, basically, caves.
That's how people have lived for thousands of years along the 1,000-foot-high cliffs overlooking the Aegean Sea, in caves hollowed out of the black and cream-colored rock. Every now and then, most recently in 1956, an eruption and earthquake reduce the houses and churches to rubble and people rebuild, always around the caves, or "traditional houses" that have long provided shelter there.
