"It's the place where they set you back down after you've been taken up in the Rapture," Sarah the English novelist said when I asked her how she was enjoying her stay at Civitella Ranieri. Then she quickly apologized, worried she might have offended me; I said, "Hell no, heavenly imagery is about all you can use to describe this place!"
"Synergy" is one of those poor words rendered nearly useless now by having been hijacked by the business world, but I think that synergy is one of the things that makes this place so magical. (Oh, "magical" is another word that doesn't mean much anymore either, but hey, I'm talking about a castle here.) The experience really is greater than the sum of its elements, and each element, taken on its own, is pretty wonderful.
