I went to a wedding at an abandoned church (I think it was at least) around St. Francisville. It was really gorgeous, but I don't know if you are going for a rustic kind of look. Also, it is a smaller venue and I don't think it has a space to get dressed or anything. Unfortunately, I can't remember the name at the moment but if I find out I will let you know.
