The original library of the Wildegg castle, with the original books. Only the closed bookcases are new, and equipped with temperature and humidity regulation.
There are 30 rooms in the castle that are open to the public and mostly they are decorated with the original furniture. And what I really, really liked, that in every room there was a real plant, a real bunch of flowers in a beautiful old vase or a wreath of real flowers. This made it as stepping in, in a real other time frame.
