Real history
The 26-room house was home to the Marquis de Mores and his wife Medora. Sources differ: the State Historical Society says it was built in 1883 and ready for Medora's arrival in spring 1884 (SHSND), while the Dickinson Press says it was completed in 1884. The Marquis was killed on June 9, 1896. The State Historical Society runs it as a historic site (Dickinson Press, 2026; Wikipedia).
Ghost stories
These are reported legends, not verified events. The creepiness score (1–5) is Spook Atlas's own editorial rating, not a measurement.
The Dickinson Press reported in 2026 on stories of a tall shadow figure in a wide-brimmed hat, children's laughter and small footsteps, a nun seen at a cradle, and a contractor who would not work alone. Site supervisor Keshna DeJesus told the paper, "To the best of our knowledge, we're actually not haunted," and said no one died in the house. Source: Dickinson Press, 2026.
