The Exorcist house exterior and the 'Exorcist steps' in Georgetown

The brick rowhouse at 3600 Prospect Street NW served as the exterior filming location for the 1973 film The Exorcist while most interior scenes were filmed in Ireland. The adjacent public staircase, commonly called the 'Exorcist steps,' is a frequent site of tours and local storytelling. Residents and visitors have long circulated anecdotes of strange noises and sightings at the house and steps; these stories are part of local folklore rather than documented paranormal evidence.
