Citizens interested in Mary Surratt formed the Surratt Society in 1975. The Surrattsville tavern and house are a historical site run today by the Surratt Society. It is devoted to mid-19th century Maryland life and the Abraham Lincoln assassination, especially to conspiracy theories surrounding the Lincoln assassination which tend to exonerate Mrs. Surratt. Some of the furniture and decorative artworks in the house are originals owned by Mary Surratt. The James O. Hall Research Center is located there.
