The "Chateau Amon Re" is also a well known place in the urban exploration community. It is a beautiful castle in a very good state. There are absolutely no trace of vandalism (at least when I went there...). It's been classified as a historic place, probably due to its architecture. I don't know what are the plans for it, but when I explored it, it was of course still abandoned, and with no trace of renovation for the near future. Its nickname "Amon Re" comes from a room in the castle where the walls are covered with egyptians drawings.
