Santorini Cliff-Side (Greece)

Santorini has made good use of its seaside real estate, even where it isn’t much more than a cliff face. These houses, hotels, and businesses have existed for centuries, precariously balanced atop the rock. Not only is Santorini gorgeous, but its terrain also affords the island's properties cave-like temperatures in the summer, making even the hottest days bearable inside. With views like this, it’s no wonder that so many people call the island a little slice of paradise.
