I see that you have two unknown , unpictured castles listed for Missouri and thought I would add mine to the list. About 25 years ago I went to a place billed as a castle near Herman, MO, which turned about to be an unfinished home and a man was using the proceeds of visitors to finish it. But, it was quite an impressive house with a turret, six stories tall and made of stone or brick.
Does anyone have any information about it? Is there someplace that I can get a picture? Any info would be appreciated.
