I think they can't be taken down because they are on the national register of historic places.
Not necessarily true. There have been instances where a listed property has been demolished despite it having historic status although I'm not up to date with all the legalities surrounding such a designation. Remember what happened to the Kahiki in Columbus, OH this past summer!
Weemes: Yes, way back when, those dorms were a hotel. I think it originally opened as the White House or something like that, later remodeling and additions changed it to The Cedars. Does anybody know when it shut down as a hotel?
