There aren’t many castles in the United States, but there is at least one in Colorado. The Bishop Castle has been under construction for quite a few decades and is the fruit of labor from one man. Jim Bishop bought the property and ultimately ended up building a castle upon it. He was challenged multiple times by authorities over rights of the building materials and zoning requirements, but the castle still stands strong.
A couple friends and I drove down from Wyoming to central Colorado where the castle is located at and checked it out.
