"Open air". A few months ago a resting place for kings, several generations, burnt down in southern Africa. In western standards the building wasn't really that stable or comfortable as it was built by straw and hey, but now on the "list" of one of the World's most important buildings. As of the strange workers doing, that building was luckily the first on the list to have been "scanned" with newest technlogy. And it can be - and will be raised again with money from far away, just because some intelligence found that particular building a fair cultural monument.
Open air for me, would be monuments actually so old that anyone should feel uncomfortable, like the pyramids of Geeza. But I can pause anyone with the probable fact: that everywhere in Europe, there are open air monuments older than the Egypyian pyramids. But not just that grand or spectacular in size. You only need to know what to look for :)
Hey! Thanks for the photo. While seeing the more traditional and exceptionally colorful Cranachs and Waffenrocks that people make are nice. I find that, from time to time, seeing a more neutral Cranach is nice (because they did exist) and occasionally bit easier on the eyes. (Some of the men's color combinations are just a bit too much for me.
