"Folly"

Postcard from Merion

Folly is a word we don't use much anymore except to describe these structures with no other purpose than to decorate the landscape—or, as in this case, define the vista and make elegant shadows.

Perhaps it is because so much of what we do is 'foolish and lacking in good sense' that the word has lost its defining power. This folly at Chanticleer provides a welcome oasis of shade in the midst of the lovely gardens, so in the real sense of the word it is not "folly" at all.
