Fascinating, and definitely useful. The castles---they seem a bit too traditional for Ages, which are generally known for being rather surreal. But the domes, the pillars, and especially the standing rock with the symbol... very nice.
This is not something that I personally have put together, but a friend of mine recently shared a link: "The 33 most Beautiful Abandoned Places in the World." If there are two things I think of when I think of Ages, it is "beauty" and "abandoned."
