Highfields was the home of Charles and Anne Lindbergh, the famous aviators. It was the location of the Lindbergh kidnapping, after which it was turned into a rehabilitation center. The home was added to the National Register of Historic Places in 1994.
Highfields, the former home of the Lindbergh family, became accessible to the public.
As a rehabilitation center, Highlands did become public as well as an Historic Site.
