Last month I posted on the Oak Brook castle that was looking for a king. Apparently kings are in short supply because they just dropped the price by $200,000. It is now listed at $4.75 MM so get your checkbooks ready. The castle is located at 3015 Lincoln Rd in Oakbrook. That's a new link because they created a new listing with this price drop. That doesn't hide the fact that the castle has been on the market for 724 days now. Here is a photo to refresh your memory of medieval times.
