The Shrine of the Book at the Israel museum. The Dead Sea Scrolls are held inside this oddly shaped building. If you look closely, you can see jets of water spraying the roof of the building. This is done to cool the building as the inside must be maintained to precisely the same enviornmental conditions as the caves where the scrolls were found, or else they will deteriorate. The inside of the building is designed to be cave-like.

On a personal note: I did not fit well through some of the doors - they're just too damned short! This has been a common problem for me in Israel as many doors are not built as tall as their American counterparts.
