The Exorcist house and the Georgetown 'Exorcist Steps' folklore

The rowhouse used for exterior shots of the MacNeil residence in the 1973 film The Exorcist is located at 3600 Prospect Street NW in Georgetown, and the nearby steep brick stairway (commonly called the 'Exorcist Steps') appears in the film. The sites have generated local ghost stories and tour narratives claiming paranormal activity, but those accounts are folklore and not supported by documented evidence. Both the house exterior and the steps remain tourist points tied to the movie's cultural legacy.
