Secret passageways abound in this early 20th century castle near the Canadian border. It was originally built for the president of the Singer Sewing Machine Co., Frederick G. Bourne, by renowned architect Ernest Flagg. The five-story, 28-room castle, aptly named Singer Castle, has stone spiral staircases, copper gutters and a castle dungeon. Uniquely situated on one of the St. Lawrence Seaway's Thousand Islands, the property offers two boathouses, a beach and a sizable squash court.

You want to go dutch on it? No,no,wait, I forgot temporarily that you prefer hills far above the element of water.LOL.
I bet the thread castle has a dungeon, but likely with very high tech laser enclosures ( Cross the line and its roast ‘roo on the floor).
