Thank you for maintaining your very interesting database of castles in the US. One castle I think you're missing is the Fortress building on the Epic Systems campus in Verona, near Madison, WI. Epic is a healthcare IT company with a crazy campus with buildings in many different themes. The Fortress building is part of the so-called Wizarding Campus.
